Exploring Ecosystem Interactions and Food Webs

What typically does not cause a species to enter a new habitat?

• Climate change

• Natural migration

• Urban development

• A polar bear wandering into the Sahara

What is an ecosystem?

• Interactions between living and nonliving components

• A static environment without changes

• Interactions between living organisms

• A community of only living organisms

What happens when a link in a food web is threatened?

• Only the immediate predators are affected

• It has no effect on the ecosystem

• It can disrupt the entire ecosystem

• It increases biodiversity

Why are spider monkeys important to the rainforest?

• They control insect populations

• They are the largest animals in the forest

• They prey on many animals

• They help in seed dispersal

Why should we avoid disrupting food webs?

• It increases ecosystem productivity

• It has minimal real-world impact

• It can lead to irreversible changes

• It is beneficial for human activities
