Ecosystems - Biodiversity & Resilience

What is BIODIVERSITY ?

Ecosystems - Biodiversity & Resilience

Biodiversity - variety of life in the world or in a particular ecosystem.

​

Biologically diverse communities are more likely to have species that confer resilience to that ecosystem because as a community accumulates species, there is a higher chance of any one of them having traits that enable them to adapt to a changing environment.

​Resilience - the ability of ecosystems to resist permanent structural change and maintain ecosystem functions.

Multiple Choice

All living and nonliving things in a particular area are called a(n)

• food chain
• life cycle
• community

• ecosystem

Multiple Choice

Which habitat exhibits the greatest biodiversity?

• A habitat with 15 different species with about 300 individuals each
• A habitat with 10 different species with about 75 individuals each
• A habitat with 4 different species with about 150 individuals each
• A habitat with only one species with about 2000 individual

Multiple Choice

Why is biodiversity so important?

• Because all species depend on each other to survive, so if one becomes extinct another species that relies on it could go extinct as well
• Because it’s better to have only one variation of each species.
• Because it better to only have a few species on Earth.
• Honestly, I have no idea what biodiversity is!

Multiple Choice

What factor does NOT affect biodiversity?

• Climate change

• Planting Native Plants
• Overfishing
• Pollution

Multiple Choice

• Biodiversity

Multiple Choice

• Food Chain

• Food Web

Multiple Choice

What has a higher biodiversity: a temperate forest or a frozen tundra?

• Frozen Tundra

• Temperate Forest

• They have a similar biodiversity

Multiple Choice

In general, as you move from the equator to the poles, what happens to biodiversity?

• Increases

• Decreases

• Remains the same

Multiple Choice

Why is biodiversity in an ecosystem so important?

• Because it can help humans where to determine good places to develop farm land.

• Because places that have a healthy biodiversity are unaffected by major disturbances.

• Because having a high biodiversity allows ecosystems to withstand major changes.

• Because having a high biodiversity allows for fewer opportunities of competition for similar resources.

Multiple Choice
