Carbon Cycle
his process by plants removes carbon dioxide from the atmosphere.
photosynthesis
This is the process of water changing from a liquid to a gas.
evaporation
This type of organism makes its own food using sunlight.
producer
A food web is made up of many of these linked together.
food chains?
The position an organism occupies in a food chain is called this.
trophic level?
Animals release carbon dioxide into the air through this process.
respiration
Clouds form during this stage of the water cycle.
condensation
Animals that eat only plants are called this.
herbivores
This term describes an animal that eats both plants and animals.
omnivore?
Plants are always found at this trophic level.
first trophic level?
Burning fossil fuels adds this gas to the atmosphere.
carbon dioxide?
Rain, snow, sleet, and hail are all forms of this.
precipitation
This is the first consumer in a food chain.
primary consumer?
This is the term for a diagram that shows how food chains overlap in an ecosystem.
food web?
Only about this percentage of energy is passed from one trophic level to the next.
10%?
This process returns carbon to the soil after plants and animals die.
decomposition?
This process moves water from plants to the air.
transpiration
These organisms break down dead plants and animals.
decomposers?
This type of consumer is at the top of a food web and has no natural predators.
apex predator?
Animals that eat herbivores are called this.
secondary consumers?
This term describes the movement of carbon between living and nonliving parts of the environment.
carbon cycle
The continuous movement of water on, above, and below Earth's surface is called this.
water cycle?
The direction of these arrows in a food chain shows the flow of this.
energy?
: What happen to the food chain if an organism randomly disappears?
disruption?
Carnivores that eat other carnivores are called this.
What is a tertiary consumer?
