Understanding Ecosystems and Ecological Roles

What is the main purpose of tasks performed by living things in their environment?

• To eliminate abiotic factors

• To compete with other species

• To create vibrant ecosystems

• To entertain other organisms

Which of the following best describes a community?

• A single organism's habitat

• Different species interacting in an area

• All the abiotic factors in an area

• A group of the same species living together

Why is it important to study populations?

• To identify abiotic factors

• To observe changes over time

• To understand individual behaviors

• To classify ecosystems

What is the primary role of producers in an ecosystem?

• To regulate oxygen levels

• To consume other organisms

• To decompose organic matter

• To produce food through photosynthesis

Which process do producers use to create food?

• Cellular respiration

• Photosynthesis

• Fermentation

• Decomposition

What type of consumer only eats plants?

• Decomposer

• Herbivore

• Omnivore

• Carnivore

How do consumers contribute to the ecosystem?

• By producing oxygen

• By regulating populations

• By consuming abiotic factors

• By decomposing organic matter

What role do decomposers play in an ecosystem?

• They consume other organisms

• They compete for resources

• They break down dead matter

• They produce food

Which of the following is an example of a decomposer?

• Bear

• Wolf

• Fungi

• Rabbit

What happens when decomposers break down organic matter?

• Nutrients are recycled

• Ecosystems are destroyed

• Producers are eliminated

• New species are formed
