What are ecosystems?

• Communities of living organisms and their interactions with their environment.

• The study of rocks and minerals.

• Groups of animals that live together in a specific area.

• The process of converting sunlight into energy.

What is primary succession?

• The process of ecological succession that occurs in an area that has been previously colonized but has been disturbed or destroyed.

• The process of ecological succession that occurs in an area that has a high biodiversity.

• The process of ecological succession that occurs in an area that has never been colonized before.

• The process of ecological succession that occurs in an area that has a low nutrient content.

Define secondary succession.

• The process of ecological succession that occurs in a previously uninhabited area.

• The process of ecological succession that occurs in a primary forest.

• The process of ecological succession that occurs in a marine ecosystem.

• The process of ecological succession that occurs in a previously inhabited but disturbed or destroyed area.

How are ecosystems formed?

• Ecosystems are formed through geological processes.

• Ecosystems are formed through human intervention.

• Ecosystems are formed through random chance.

• Ecosystems are formed through ecological succession.

Why is biodiversity important for ecosystems?

• Biodiversity ensures stability and resilience of the ecosystem, provides various species for different roles, and enhances overall productivity and health.

• Biodiversity only benefits certain species, not the entire ecosystem.

• Biodiversity has no impact on ecosystems.

• Biodiversity leads to overcrowding and competition within ecosystems.

What are the stages of primary succession?

• Shrubs and small trees establish, pioneer species colonize, mosses and lichens break down rocks, grasses and small plants grow.

• Grasses and small plants establish, larger trees and diverse ecosystem develop, pioneer species colonize, mosses and lichens break down rocks.

• Mosses and lichens establish, shrubs and small trees grow, pioneer species colonize, diverse ecosystem develops.
