Ecosystems

Where do plants get the energy from to make food?

• Photosynthesis

• Sun

• Animals

• Metamorphosis

Biotic Factors include (types of organisms)

• Rocks

• Cells

• Energy

• Water

What is the study of Ecology?

• A thing that makes up their surroundings

• Organism that feed directly or indirectly on producers

• Relationships and other interactions with other organisms

• The study of the earth

What is an ecosystem?

• All the interacting organisms that live in an environment and the abiotic parts of the environment that affect the organisms

• A person who observes and studies the interactions between the biotic and abiotic parts of the environment

• The relationship among the biotic parts of the environment

• The relationship between all the abiotic elements of a pond

When populations share their environment and interact with populations of other species, it is called a

• Biome

• Ecoprovince

• Community

• Species

• Ecotone

A consumer is

• An organism that produces its own food

• An organism that does not need food to survive

• An abiotic organism

• An organism that cannot produce its own food

A food web is more realistic than a food chain for showing the feeding relationships in ecosystems because

• It compares the number of consumers to the number of micro-organisms in an ecosystem.

• Food chains use only a small sampling of organisms.

• A food web explains why there are more producers than consumers.

• Producers are usually eaten by many different consumers and most consumers are eaten by more than one predator.

Choose the phrase that correctly finishes this statement: "A species is..."

• A specific part of the abiotic environment

• A way of describing all the living part of an ecosystem

• A group of organisms that can successfully mate with each other and reproduce

• Part of the natural decomposing materials in soil

What are the 3 main energy roles in the environment?

• Producers, consumers, and decomposers

• Herbivores, carnivore, and omnivore

• Consumer, producer, scavenger

• None of the above

The space where an organism lives and the role an organism plays within its ecosystem is referred to as a

• Sampling

• Community

• Population

• Niche

• Biosphere
