Matter and Energy in Ecosystems

What are decomposers?

• Organisms that produce energy through photosynthesis.

• Organisms that break down dead or decaying organisms, returning nutrients to the soil.

• Organisms that consume living plants and animals.

• Organisms that filter water and purify the environment.

What is matter?

• Matter is anything that has mass and takes up space.

• Matter is a type of energy that can be converted into mass.

• Matter is a substance that can only exist in solid form.

• Matter is a concept that describes the absence of physical substance.

What are ecosystems?

• Ecosystems are communities of living organisms interacting with their environment.

• Ecosystems are isolated areas with no interaction between organisms.

• Ecosystems are only found in tropical regions.

• Ecosystems are artificial environments created by humans.

What is energy?

• Energy is the ability to do work or cause change.

• Energy is a measure of temperature.

• Energy is a type of matter.

• Energy is the force exerted by an object.

What gas do plants take in during photosynthesis?

• Oxygen

• Nitrogen

• Carbon dioxide

• Hydrogen

What role do decomposers play in an ecosystem?

• Decomposers recycle nutrients back into the ecosystem by breaking down dead matter.

• Decomposers produce energy through photosynthesis.

• Decomposers compete with plants for sunlight and nutrients.

• Decomposers create new species by evolving from dead matter.

What is the carbon cycle?

• The process by which carbon is exchanged between the atmosphere, land, water, and living organisms.

• A method of carbon capture and storage in geological formations.

• The cycle of carbon emissions from industrial activities.

• The process of photosynthesis in plants.

What are producers in an ecosystem?

• Organisms that can make their own food, typically through photosynthesis.

• Organisms that consume other organisms for energy.

• Organisms that decompose dead matter.

• Organisms that rely on external sources for food.

What are energy storage molecules?

• Compounds that store energy for later use, such as glucose.

• Molecules that are used for immediate energy release, like ATP.

• Substances that only exist in plants for photosynthesis.

• Elements that cannot store energy at all.

What is the significance of sunlight in ecosystems?

• Sunlight is the primary energy source for most ecosystems, driving photosynthesis.

• Sunlight is a secondary energy source that supports animal life.

• Sunlight has no significant role in ecosystems.

• Sunlight is primarily used for heating the atmosphere.
