The Water Cycle (plus)
100
The definition of Ecology.
What is the scientific study of interaction among organisms and their environment.
100
The main source of energy for all living things on Earth.
What is the sun?
100
The type of consumers that eat nothing but plants.
What are herbivores?
100
The percentage of energy that is transferred from one trophic level to the next in the energy pyramid.
What is 10%?
100
The scientific word for rain, snow, sleet or hail in the water cycle.
What is precipitation?
200
Groups of individuals of the same species in an environment.
What is a population?
200
These organisms make their own food via photosynthesis, and make up the bottom section of the energy pyramid.
What are producers?
200
This type of consumer only eats meat- such as a lion.
What is a carnivore?
200
The measurement used for the amount of energy in a trophic level.
What are joules?
200
Scientific term for the clouds or fog in the water cycle.
What is condensation?
300
A collection of all the organisms that live in an area as well as their environment.
What is an ecosystem?
300
Unlike autotrophs that make their own food from the sun, this is another name for consumers.
What are heterotrophs?
300
You are this type of consumer, because you are able to eat both plant and animal organisms.
What is an omnivore?
300
A pyramid of numbers simply shows this at each trophic level.
What is the numbers of individual organisms?
300
One of the ways water goes back up to the clouds, where gas forms from liquid in bodies of water.
What is evaporation?
400
A group of ecosystems that have the same climate and dominant communities.
What is a biome?
400
The path of energy that is passed along linearly from producers to consumers in an ecosystem.
What is a food chain?
400
These organisms are considered consumers because they get their nutrients by breaking down organic matter, such as bacteria and fungi.
What are decomposers?
400
A biomass pyramid represents the total amount of this in a given trophic level.
What is the amount of living tissue or potential food available?
400
One of the ways water returns to the clouds, coming from the leaves of plants.
What is transpiration?
500
The six levels of organization in Ecology in order.
What is the individual, population, community, ecosystem, biome, and biosphere?
500
A more complex example of the path of energy in an ecosystem, with multiple feeding relationships.
What is a food web?
500
Mites, earthworms, snails and crabs feed on the remains of dead plants and animals. They are this type of consumer.
What are detritivores?
500
This is the amount of energy at the tertiary level if the producer level contained 20,000 joules.
What is 20 joules?
500
This is the key ingredient in all living organisms, also found in the oceans, air, and rocks.
What is carbon?
