When an ecosystem loses biodiversity How does it change?

A decrease in biodiversity causes a decrease in ecosystem stability, because a change to one organism will have a greater impact on the entire ecosystem. With greater biodiversity, the loss of one type of organism could be moderated by the adaptation of other organisms to fill its role.

Which is the final and most stable stage of change in an ecosystem?

An ecological community in which populations of plants or animals remain stable and exist in balance with each other and their environment. A climax community is the final stage of succession, remaining relatively unchanged until destroyed by an event such as fire or human interference.

The Importance of 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.
  • Protect freshwater resources.
  • Promote soils formation and protection.
  • Provide for nutrient storage and recycling.

What are the 5 threats to biodiversity?

Five main threats to biodiversity are commonly recognized in the programmes of work of the Convention: invasive alien species, climate change, nutrient loading and pollution, habitat change, and overexploitation.

What are the effects of biodiversity loss?

Biodiversity underpins the health of the planet and has a direct impact on all our lives. Put simply, reduced biodiversity means millions of people face a future where food supplies are more vulnerable to pests and disease, and where fresh water is in irregular or short supply. For humans that is worrying.

  • Altering habitats. Hunting.
  • Invasive Species. Pollution.
  • Driving Climate. Change.

What are four ways that human activity can reduce biodiversity?
