What level of school?\n\nHumans eat plants, and sometimes animals as food. \n\nPlants are used to provide medicines and materials for construction. \n\nPlants protect the soil from erosion.\n\nPlants make oxygen for humans to breathe. \n\nPlants give us shade and places for animals to live. \n\nAnimals are human companions, and used to be a primary source of power. In some parts of the world, animals are still used for power and transportation. \n\nAnd so on.

It would take a while to look up, but the mineral content does not vary significantly between any mammals, so human mineral content would be sufficient.  In fact, I doubt if the mineral content varies more than a tiny amount between mammals and birds.

most plants are producers\nmost animals are consumers\nmany insects are decomposers\nmany fungi and molds are decomposers too\n\n\njust think of common plants and animals and you'll do fine for those catagories

The sources of energy to animals (including humans) are carbohydrates, lipids, and proteins.  Carbohydrates include sugars, starches, and cellulose.\nHumans can digest proteins, lipids, sugars and starches, but not cellulose.  So, we can get energy by eating plants (or parts of plants) that contain proteins, lipids, sugars, and/or starches.  We can't get energy from sources that only have cellulose.  For instance, we don't get any energy from celery or lettuce, though we can get vitamins and minerals, maybe some other nutrients also.  \nRabbits, horses, and cattle eat large amounts of plants containing cellulose as the main energy source.  They carry microorganisms in their intestines that help them digest the cellulose, breaking it down into sugars.  Some microorganisms further process these into proteins.  However, humans don't host this kind of microorganism.

some plants are beautiful, some are edible, so it is a good idea ot to be ignorant of what kind of vegetables/nuts, ets are what\n\nthen pls realize that virtually al organic matter (and all energy bound in it) in the world originated through photosynthesis. A cow cannot produce organic matter from nothing so the steak that gives u strenght and nutrients is here because the cow ate plants. your car runs on petrol from oil, your clothes are cotton or synthetic fibre from oil , oil comes from prehistoric organisms whose bodies were formed thanks to eating other creatures who ate other creatures who ate plants. etc etc.\n\nthat is what i say whenever asked this. i have studied it in college and for me the ood thing is that vegatation to me is not just green mass, but distinct plant species, so the difference is like when u walk through a crowd of unknown people or you are among people that u recognize. it is great when you can be outdoors and say - look i know that flower/tree, i know something about it\n\nif your botany lessons are very boring, pick up only the information that could be useful to your health - like poisonous or allergenous plants that can grow nearby. like how would u feel if u had a child and it chewed a flower in the garden or in a vase and got sick/died only because u were not aware thet it is poisonous. many ornamental plants are so they are often grown in gardens and u should know which are they in case children are around (not necessarily your children of course) babies can put things in mouth in no time!

Well whether or not it was discovered doesn't really matter. The fact that there is a symbiotic, mutualistic relationship between plants (producers) and all other organismsis quite important.  The plants depend on humans and animals for CO2 (carbon dioxide) which we exhale as a by-product of cellular respiration. \n\nThe plants in turn use that to build simple starches as their food source through the process of photosynthesis.  Then the by-product of the plants cellular respiration is Oxygen which the humans and animals all need to survive.\n\nIf we as humans didn't understand this important relationship that exists we in our ignorance may destroy the plant life that exists on earth (think Amazon Jungle and deforestation).  Without the plants we have no oxygen, without oxygen we DIE!\n\nThat's pretty significant don't you think?

A food web would go from the simplest form of life [the producer] to consumers. First draw the sun. Draw an arrow from the sun to a plant. Draw an arrow from the plant to an animal that eats it. Draw an arrow from the animal to an animal that eats the first animal. You can make it more complex and have more than one path of arrows.\n\nExample: Sun -> Grass -> Cow -> Human\n\nSun -> Grass -> Grasshopper -> Spider -> Bird\n\nYou can link these two.

Well, it depends on which organisms you are looking at. First of all, light/the sun is absolutely essential for all life on the planet, as the sun provides the energy for photosynthesis to take place, which allows the production of glucose. This glucose is then transmitted to consumers who eat the plants.\n\nin terms of humans, light/sunlight is actually pretty essential for the production of vitamin D, because radiation from the sun actually causes skin cells to produce Vitamin D. A deficiency in this vitamin can cause rickets or osteoporosis. So, basically sunlight is important for humans for normal bone growth. Also, the light also affects how light/dark one is, because of tanning. Tanning/darkening of the skin occurs when the body creates more melanin to protect the body.

I would just talk about way plant and animal cells are constructed like cell walls and stuff. And talk about differences in how they make energy like animals burn sugar and plants first make sugar themselves. I'm sure that could be used to discuss nutrients issues.

>Plant do not contain much organelles inside the cell\n so they posses large vacuoles in their cytoplasm.\n>Where as animals as more cell organelles in their cell\n They store some bio-molecules which is required for them during the necessary period like starvation.\nso animals do not have vacuole.\n\n>Plants are auto-tropic which can synthesis their own food.\nplant get their food by photosynthesis which is the       biochemical process. \nThe chloroplast plays the major role in photosynthesis.\n>Animal is an hetero-tropic depend on other for food.\nso they don't need chloroplast.\n\nchloroplast contains chlorophyll pigment which is green coloured pigment also make the plants to appear green.\nso animal do not require chloroplast anyway.

B) Oxygen\n\nhttp://www.aspb.org/publications/biotext/sumrys/ch12.cfm\n\nWhich is a major reason green plants are our friends!  They take in our waste gas (CO2) in the process of photosynthesis which produces THEIR waste gas, O2, which WE need.\nNow look up the word "symbiosis" as a term to describe that relationship!\n(Glycogen is produced in animals, not plants.)

It depends on where they're employed. They may be teachers, or they may be researchers. They may be animal caretakers.

Necessary for who?  It is certainly necessary for humans.  If it wasn't for humans, humanity in general wouldn't exist.  Maybe the rest of the planet might not miss us much, but I certainly would.\n\nWhile our presence and proliferation certainly does have a detrimental effect on many other organisms and ecosystems, it is because we create our own ecosystem.  Not many people really think about, but human cities and even rural developments have their own ecology and associated plant and animal life that thrives in contact with humans.\n\nSpecies such as rats, cockroaches and pigeons are the obvious faunal assemblage associated with human activity, but there are other species of animals that have become far more successful in association with humanity than they would otherwise have been.  Cats and dogs are far more numerous and widespread than their wild counterparts, as are chickens, sheep, cows and all of our domestic animals.\n\nThe crop species, like wheat, corn, rice and other have also benefited immensely from human cultivation.  The wild counterparts of broccoli and banana are not nearly as successful.\n\nThere are also species who have been able to expand their range as the human ecosystem pushes competitors farther afield.  Coyotes, raccoons, opossums, tree squirrels, house sparrows, starlings, and even white tailed deer have all benefited as the human ecosystem takes over what was formerly plains or forest ecosystem.  Other species like elms, palm trees, oaks and ash used to line our city streets have also expanded their range.\n\nWhile it's not exactly great for biodiversity, the human ecosystem does certainly benefit some organisms.  Without us Plasmodium (the protozoan that causes Malaria) wouldn't be nearly as successful as it is.\n\nSo the Earth itself would certainly survive quite nicely without us, but that entire ecosystem of cows, wheat, cockroaches and kitty cats would be wiped out without us.  In many ways, we are a keystone species in our ecosystem.  It's just too bad that we seem to be insistent on replacing EVERY other ecosystem with our own.

Have enough picture/word cards of animals/plants in a food chain for each student to have one.  You need a big ball of yarn or string.  Put the students in a circle.  The lowest person on the food chain starts.  They hold the string and throw the ball to the next highest person on the chain (preferably, they are not sitting in order).  That person holds on to the string and tosses the ball to the next person.  \n\nAt the end, you've formed a web of interconnected species.  To simulate environmental changes, have a few students drop their part of the web.  It will fall and dissinigrate showing how a healthy ecosystem is dependant on all of its occupants.\n\nHope that helps.

plants need minerals as their food through the process of photosynthesis as people need minerals, vitamins, carbohydrates, protein fats , oil, etc as food through the process of digestion and assimilation

Because animals don't have to accomplish as many tasks, so they can specialize on a few specific tasks and learn to perfect them. Humans take on a greater number of tasks, most of which are highly complex, so they can't specialize as easily.

water, the oxygen and the abundant food. these are basic things that human being need on the earth.so all these can be found on the earth..water from rivers.oxygen from the air and food from fruit/trees, animals etc etc.
