Exploring Ecosystem Components

What are biotic factors in an ecosystem?

• Biotic factors are the living components of an ecosystem.

• Abiotic factors are the non-living components of an ecosystem.

• Biotic factors are the physical environment of an ecosystem.

• Biotic factors are the chemical substances in an ecosystem.

How do trees (biotic) interact with air (abiotic) in an ecosystem?

• Trees eat oxygen from the air for energy.

• Trees release nitrogen into the air.

• Trees use carbon dioxide from the air for photosynthesis.

• Trees produce sunlight for other organisms.

What are the examples of Biotic Components of Ecosystem

• Water

• Plants, animals, microorganisms

• Rocks

• Sunlight

What are some common abiotic components found in nature?

• Bacteria, fungi, viruses

• Sunlight, water, air, soil, minerals

• Rocks, trees, animals

• Clouds, temperature, gravity

These are animals that eat both plants and Animals

• Herbivore

• Carnivore

• Omnivore

• Decomposer

Explain the role of producers in a biotic community.

• Producers have no impact on the biodiversity of a biotic community.

• Producers are organisms that make their own food using sunlight, water, and carbon dioxide through a process called photosynthesis

• Producers are organisms that cannot make their own food.

• Producers are primarily responsible for decomposition in a biotic community.

Which of the following is an example of a producer?

• Lion

• Mushroom

• Grass Plant

• Rabbit

Identify two abiotic factors that affect plant growth.

• Sunlight, Water

• Wind speed

• Temperature

• Soil type

How does sunlight affect plants in an ecosystem?

• It helps them grow by providing energy for photosynthesis.

• It decomposes dead organisms.

• It provides oxygen for animals to breathe.

• It helps animals find food.

Which abiotic factor is MOST important for fish to survive in a pond?

• Soil

• Rocks

• Water

• Wind
