Photosynthesis
This is the process plants use to make their own food using sunlight.
Photosynthesis
This process releases energy from food in cells.
cellular respiration
Matter in ecosystems is not lost; it is __________.
Recycled
An organism that makes its own food.
Producer
What is pollution?
This is when harmful substances enter the environment.
This organelle in plant cells captures sunlight.
Chloroplast
This gas is taken in during cellular respiration.
oxygen
These organisms break down dead matter.
Decomposers
An organism that eats other organisms.
consumer
What is deforestation?
Cutting down large areas of trees.
These are the two main inputs needed for photosynthesis (besides sunlight).
Carbon dioxide & water
This gas is released during cellular respiration.
Carbon dioxide
Name one place carbon is found in the carbon cycle.
Atmosphere, plants, animals, soil, oceans
A system of many connected food chains.
food web
What is climate change?
Long-term changes in Earth’s temperature and weather patterns.
This sugar is produced during photosynthesis and stores energy.
Glucose
This is the main reason organisms need to eat food.
to get energy
What happens to matter after an organism dies?
It is broken down and returned to the environment
What would happen if producers disappeared?
The ecosystem would collapse because no energy enters the system
Name one way humans can help ecosystems.
Recycle, plant trees, reduce pollution, conserve resources
This gas is released into the air during photosynthesis.
Oxygen
Explain how cellular respiration and photosynthesis are connected.
They are opposite processes; the products of one are the reactants of the other.
Why is matter cycling important?
It allows materials like carbon and nutrients to be reused
What happens if one organism in a food web is removed?
It affects many other organisms because they are all connected
How do human actions affect ecosystems?
They can disrupt food webs, reduce biodiversity, and change matter/energy flow
