What is an organism that gets its energy by eating secondary consumers?
Tertiary consumer
If only 10% of energy moves through each level of the energy pyramid, what happens to the other 90%?
It is converted into heat and energy for all life functions.
The fact that the total mass of a dead organism equals the total mass of matter released to the environment by decomposition demonstrates which law of conservation?
Law of conservation of mass
What is a system consisting of all the interactions that occur between the abiotic and biotic factors within an environment?
Ecosystem
What is the role of a producer?
To transform energy from the sun to make food.
The law of conservation of energy states that-
energy cannot be created nor destroyed.
What are organisms that transform energy from the sun and use carbon dioxide and water to make food?
Producers
How do plants follow the law of conservation of mass during photosynthesis?
The amount of each element in the reactants equals the amount of each element in the products.
What is the ultimate source of energy for food webs?
The Sun
What are animals that eat only plants or plant products?
Herbivores
Why do most food webs only have three or four levels?
There is not enough energy to support more
What is an energy path from one organism to another showing a linked series; feeds on the one prior to it in the series?
Food chain
What is any class of organisms occupying the same position in a food chain, such as primary consumers or secondary consumers?
Trophic level
The amount of each element in the reactants of photosynthesis equals the amount of each element in the products is evidence of which law of conservation?
Law of conservation of mass
The law of conservation of matter states-
Matter can neither be created nor destroyed.
What are organisms that get their energy by feeding on producers in the food chain?
Primary consumers
What are organisms, such as bacteria and fungi, that break down the remains of dead plants and animals without need for internal digestion?
Decomposers
The fact that decomposers transfer energy stored in the molecules of the dead organism to create new biomass for other organisms to feed on is evidence of which law of conservation?
Law of conservation of energy
What are overlapping food chains with different pathways for the flow of food energy in an ecosystem?
Food web
What are organisms that get their energy by feeding on primary consumers in the food chain?
Secondary consumers
What are organisms that feed on other organisms in a food chain?
Consumers
What do we use to show how much energy transfers to the next trophic level in a food chain?
Energy pyramid
What is a carnivore?
An animal that eats other animals
