Explanation: Biodiversity is a measurement of how many different types of organisms are found in an ecosystem. The higher the biodiversity means that the ecosystem can sustain (maintain) many different types of producers, consumers, and decomposers. This generally means that the area is healthy.

Agricultural biodiversity is essential to satisfy basic human needs for food and livelihood security. ... It contributes directly to food security, nutrition and well-being by providing a variety of plant and animals from domesticated and wild sources.

Nutritional impact of biodiversity Biodiversity plays a crucial role in human nutrition through its influence on world food production, as it ensures the sustainable productivity of soils and provides the genetic resources for all crops, livestock, and marine species harvested for food.

Why is biodiversity loss a concern? Biological diversity, or biodiversity, is the term given to describe the variety of life on Earth. ... Biodiversity loss disrupts the functioning of ecosystems, making them more vulnerable to perturbations and less able to supply humans with needed services.

Our biodiversity is very important to the well-being of our planet. ... Healthy ecosystems and rich biodiversity: Increase ecosystem productivity; each species in an ecosystem has a specific niche—a role to play. Support a larger number of plant species and, therefore, a greater variety of crops.

Biodiversity is important because it provides us with Natural Resources (Food, Water, Wood, etc.) Natural Services (Pest Control, Air and Water Purification, etc.) and of course, Aesthetic Pleasure. What are the most significant threats to biodiversity?

Forests are critical habitats for biodiversity and they are also essential for the provision of a wide range of ecosystem services that are important to human well-being. There is increasing evidence that biodiversity contributes to forest ecosystem functioning and the provision of ecosystem services.

Biodiversity is the key indicator of the health of an ecosystem. A wide variety of species will cope better with threats than a limited number of them in large populations. Even if certain species are affected by pollution, climate change or human activities, the ecosystem as a whole may adapt and survive.

Biodiversity plays an important role in the way ecosystems function and in the many services they provide. Services include nutrient and water cycling, soil formation and retention, resistance against invasive species, pollination of plants, regulation of climate, as well as pest and pollution control by ecosystems.

Biodiversity provides numerous ecosystem services that are crucial to human well-being at present and in the future. ... Longer term changes in climate affect the viability and health of ecosystems, influencing shifts in the distribution of plants, pathogens, animals, and even human settlements.

Biodiversity is the basis of agriculture and our food systems. ... Agricultural biodiversity also performs ecosystem services such as soil and water conservation, maintenance of soil fertility, conservation of biota and pollination of plants, all of which are essential for food production and for human survival.

Biodiversity boosts ecosystem productivity where each species, no matter how small, has an important role to play. ... Greater species diversity ensures natural sustainability for all forms of life. Healthy ecosystems can better withstand and recover from a variety of disasters. (Insure and go, 2014)

Biodiversity is important to people in many ways. Plants, for instance, help humans by giving off oxygen. ... Plants, fungi, and animals such as worms keep soil fertile and water clean. As biodiversity decreases, these systems break down.

BIODIVERSITY is the basis of AGRICULTURE. Its maintenance is essential for the production of food and other agricultural goods and the benefits these provide to humanity, including food security, nutrition and livelihoods. BIODIVERSITY is the origin of all crops and domesticated livestock and the variety within them.

Based on tropical rainforests, we see why biodiversity is so crucial in maintaining an ecosystem. Since rainforests have huge ranges of plants, many insects or animals will have more diverse preys. ... If more organisms diversify, it ensures the natural sustainability of all life forms in the ecosystem.
