Energy Roles in Ecosystems

What is a herbivore?

• An organism that primarily eats plants.

• An organism that primarily eats meat.

• An organism that can eat both plants and meat.

• An organism that does not eat at all.

What energy role do wild pigs represent?

• Carnivore, as they primarily eat meat.

• Herbivore, as they primarily eat plants.

• Omnivore, as they eat both plants and animals.

• Detritivore, as they feed on decomposing organic matter.

What do omnivores eat?

• Only plants.

• Only meat.

• Both meat and plants.

• Only fruits.

What is a producer?

• An organism that can make its own food, typically through photosynthesis.

• An organism that consumes other organisms for energy.

• A type of consumer that feeds on producers.

• An organism that decomposes organic material.

How do food chains and food webs illustrate energy roles?

• They show the flow of energy from producers to various levels of consumers in an ecosystem.

• They depict the physical structure of an ecosystem without showing energy flow.

• They illustrate the competition between different species for resources.

• They represent the seasonal changes in an ecosystem's energy dynamics.

How do decomposers contribute to nutrient cycling?

• They produce energy through photosynthesis.

• They break down dead matter, returning nutrients to the soil for use by producers.

• They compete with producers for sunlight and nutrients.

• They store nutrients in their bodies for long periods.

What is a consumer?

• An organism that can make its own food.

• An organism that cannot make its own food and gets energy by eating other organisms.

• An organism that only eats plants.

• An organism that produces energy through photosynthesis.

What is the role of energy flow in an ecosystem?

• Energy flows from producers to consumers and decomposers, maintaining ecosystem balance.

• Energy is stored in the soil and used by plants only.

• Energy is recycled within the ecosystem without any loss.

• Energy flows only from consumers to producers.
