What is an ecosystem?

• A group of organisms that live together in harmony

• The non-living components of the environment

• All the organisms in a particular area and their interactions with the non-living components of their environment

• A community of plants and animals

How can relationships within an ecosystem be tracked?

• By observing the behavior of organisms

• By studying the abiotic factors

• By analyzing the food chain

• By measuring the temperature and humidity

How can ecosystems be protected?

• By reducing pollution and waste

• By introducing new species

• By cutting down trees

• By increasing human activities in the area

What are biotic factors in an ecosystem?

• Living things in an ecosystem including dead things and their wastes

• Non-living things in an ecosystem

• Organisms that reproduce to form populations

• The interactions between organisms and their environment

What are abiotic factors in an ecosystem?

What does an ecosystem look like?

• A large area with diverse plant and animal species

• A small area with only a few organisms

• A community of plants and animals

• All the organisms in a particular area and their interactions with the non-living components of their environment

How do organisms interact within an ecosystem?

• By cooperating to protect each other

• By fighting for the same resource/food

• By using another organism without harming or benefiting it

• By hunting/eating others for energy

Why do organisms eat?

• To gain energy

• To socialize with other organisms

• To show dominance

• To maintain body temperature

How can prey-predator relationships be tracked?

• By creating an energy flow chart

• By studying the behavior of organisms
