🌿 Ecology
What do we call an animal that eats only plants?
Herbivore
Name one type of energy.
Kinetic, thermal, light, sound, etc.
What are reactants?
Substances you start with in a reaction
Name one type of force.
Gravity, friction, air resistance, etc.
What is photosynthesis?
How plants make food using sunlight
What is the atmosphere?
A layer of gases around Earth
What is a consumer in an ecosystem?
An organism that eats other organisms
Name one type of wave.
Sound wave, light wave, water wave, etc.
What is the difference between a physical and chemical change?
Chemical = new substance; physical = no new substance
What is mass?
The amount of matter in an object
What gas do plants take in during photosynthesis?
Carbon dioxide (CO₂)
What is the greenhouse effect?
Traps heat in Earth’s atmosphere
What is the difference between a food chain and a food web?
Food chain = one path; food web = many paths
What is the law of conservation of energy?
Energy cannot be created or destroyed
What are the three things needed for combustion?
Fuel, oxygen, heat
What is voltage?
The push that makes current flow
What is pollination?
Transfer of pollen to another flower
What is global warming?

What is amplitude in a wave?
The height of the wave from the middle line
What is oxidation?
When a substance reacts with oxygen
What is the difference between series and parallel circuits?
Series = one path; Parallel = multiple paths
Why is light important for photosynthesis?
It provides energy to make food
What causes acid rain?
Pollution from burning fuels
What is bioaccumulation, and why is it dangerous in food chains?
Toxins build up and get stronger up the food chain
What is refraction?

What is the conservation of mass?
Mass stays the same before and after a reaction
What is the unit of force?
Newtons (N)
What is the role of stomata?
Tiny holes for gas exchange
What are fossil fuels and why are they a problem?
Coal, oil, gas – cause pollution
