Understanding Ecosystems
100

Which level consists of individuals of the same species living in the same area?

Population

100

What is a herbivore, and what is its main source of food?

An animal that eats only plants.

100

What is a habitat?

The place where an organism naturally lives and grows.

100

What does biodiversity refer to?

The wide range of species and the way they interact with each other and their environment.

100

What is an ecosystem?

A community where living things, such as plants, animals, and microorganisms, interact with non-living things like soil, water, and sunlight.

200

Arrange these from smallest to largest: population, community, ecosystem, biome, individual.

Individual, Population, Community, Ecosystem, Biome.

200

What is a carnivore?

An animal that eats only meat.

200

What term refers to a group of interacting individuals of the same species?

Population

200

Which biome has the highest biodiversity?

Tropical rainforest.

200

What role do producers play in an ecosystem?

Producers, like plants, make their own food through photosynthesis, providing energy for other organisms.

300

What level of ecological organization includes multiple communities in a large geographic area?

Biome

300

Which type of animal only eats other animals?

Carnivore

300

What is a Microhabitat

A very small, specialized habitat, such as the space under a rock.

300

What does a biome represent in an ecosystem?

A type of biological community defined by its predominant plants, animals, and environmental conditions.

300

Name one way decomposers contribute to ecosystems.

Decomposers break down dead matter, returning nutrients to the soil.

400

What level of ecological organization involves all living and non-living components of an area?

Ecosystem

400

How do omnivores contribute to ecosystems?

They help balance ecosystems by eating both plants and animals.

400

What is the term for all populations of organisms that live together in the same area?

Community

400

Which habitat type is found at the bottom of ponds or rivers?

Benthic zone.

400

Describe one step in the water cycle.

Evaporation: The sun heats up water in rivers, lakes, and oceans, turning it into vapor that rises into the air.

Condensation: As the water vapor cools in the atmosphere, it forms tiny droplets, creating clouds.

Precipitation: When the droplets in clouds get heavy, they fall to the ground as rain, snow, sleet, or hail.

Collection: The water collects in bodies like rivers, lakes, and oceans, or soaks into the ground to become groundwater.

Runoff: Water flows over the land, returning to rivers, lakes, and oceans, where it can evaporate and start the cycle again.

500

In which level of ecological organization do different species live together and interact?

Community.

500

Name an example of an omnivorous animal.

Bears (or any other Omnivorous animal)

500

What defines an ecosystem?

A system comprising all the biotic and abiotic factors in an area and all the interactions among them.

500

What type of habitat is found under rocks and logs, providing shelter for small organisms?

Microhabitat

500

Explain the concept of interdependence in ecosystems.

All organisms rely on one another to survive; for example, plants provide oxygen, decomposers return nutrients to the soil, and animals contribute to food webs.
