Ecosystem Ecology

Mr. Anderson's video on Ecosystem Ecology covers the organization of life from individuals to the biosphere, focusing on ecosystems and their components. It explains the role of keystone species, the characteristics of terrestrial and aquatic biomes, and the importance of biodiversity. The video also discusses the concept of niches, food webs, and the impact of edge effects on ecosystems. It concludes with a recap of key points and a learning check.

In a food chain, what does the direction of the arrow represent?

• The speed of consumption

• The size of the organism

• The flow of energy

• The age of the organism

What is a niche in an ecosystem?

• The role or job of an organism

• The physical space an organism occupies

• The lifespan of an organism

• The food an organism consumes

Why is species diversity important in an ecosystem?

• It enhances ecosystem resilience and health.

• It makes ecosystems more vulnerable to changes.

• It increases competition for resources.

• It reduces the number of predators.

What is the edge effect in an ecosystem?

• The boundary between two ecosystems

• The effect of pollution on ecosystems

• The impact of climate change on ecosystems

• The influence of human activity on ecosystems
