How does low or high biodiversity affect an ecosystem?

Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change.

How does low biodiversity affect an ecosystem?

Declining biodiversity lowers an ecosystem’s productivity (the amount of food energy that is converted into the biomass) and lowers the quality of the ecosystem’s services (which often include maintaining the soil, purifying water that runs through it, and supplying food and shade, etc.).

What does high or low biodiversity mean to an ecosystem which is best?

Higher/more biodiversity = more sustainable. • Lower/less biodiversity = less sustainable. • High biodiversity in an ecosystem means that there is a great variety of genes and species in that ecosystem.

What are the results of high biodiversity low biodiversity?

When an ecosystem has a high level of biodiversity, it is always more stable than when it has a low level of biodiversity. … The productivity of an ecosystem (the quantity of food energy turned into biomass) and the quality of ecosystem services get affected by declining biodiversity.

Is high biodiversity good or bad for an ecosystem?

Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, A larger number of plant species means a greater variety of crops. … Healthy ecosystems can better withstand and recover from a variety of disasters.

Why is biodiversity important to ecosystem?

Biodiversity is important to humans for many reasons. … Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services.

Why is low biodiversity bad?

Biodiversity loss can have significant direct human health impacts if ecosystem services are no longer adequate to meet social needs. Indirectly, changes in ecosystem services affect livelihoods, income, local migration and, on occasion, may even cause or exacerbate political conflict.

Is it better to have a high or low biodiversity?

High biodiversity, with many species present, is good. It usually means that an ecosystem is healthy and relatively undisturbed by humans. Low biodiversity is characteristic of an unhealthy or degraded environment. A mown lawn in a city park is an example of an ecosystem with low biodiversity.

What does high biodiversity mean for an ecosystem?

Biodiversity refers to the variety of life. When biodiversity is high, it means there are many different types of organisms and species. … And every organism plays a unique role and contributes to how coral reef communities survive and function.

What is an ecosystem with high biodiversity?

Example of ecosystem with high biodiversity is tropical rain forest as seen in Amazon basin of south America. Such forests are also thriving in parts of central Africa and also in islands of Indonesia. In marine environment, coral reefs are example of high biodiversity aquatic ecosystems.

How does biodiversity affect ecosystem services?

Many key ecosystem services provided by biodiversity, such as nutrient cycling, carbon sequestration, pest regulation and pollination, sustain agricultural productivity. Promoting the healthy functioning of ecosystems ensures the resilience of agriculture as it intensifies to meet growing demands for food production.

What are the negative effects of biodiversity?

2.1 Biodiversity loss has negative effects on several aspects of human well-being, such as food security, vulnerability to natural disasters, energy security, and access to clean water and raw materials. It also affects human health, social relations, and freedom of choice.

How will increasing species diversity affect ecosystem?

Explanation: By increasing species diversity in an ecosystem, both the efficiency and the productivity of an ecosystem will increase. A greater species richness and diversity may cause ecosystems to function more efficiently and productively by making more resources available for other species.
