Ecosystem Structure
A species whose removal would significantly impact an ecosystem.
What is a keystone species?
This is copied during Mitosis.
What are chromosomes?
An organism that eats only plants.
What is an herbivore?
The process plants use where one of the reactants is the Sun.
What is photosynthesis?
The simplest diagram of how energy is transferred between organisms.
What is a food chain?
The same species living in one area.
What is a population?
A form of a gene that is used to identify parents.
What are alleles?
Organisms that make their own food.
What is a producer?
Both plants and animals use this process to convert sugar into ATP energy.
What is cellular respiration?
In a food web, the arrow points in the direction that this is moving.
What is energy?
Two categories that separate all things in an ecosystem.
What are abiotic and biotic factors?
This type of fingerprinting is used to identify where organisms originated.
What is DNA fingerprinting?
The feature of a digestion system that indicates diet.
What is length?
The process that makes two identical cells.
What is mitosis?
The trophic level that has the most energy available.
What is Trophic Level 1?
When an ecosystem is in balance.
What is homeostasis?
Populations that live in areas that are geographically near each other may have this in common.
Proteins are made of these types of molecules.
What are amino acids?
The phase in mitosis when chromosomes line up in the center of the nucleus.
What is metaphase?
The source of all energy on Earth.
What is the Sun?
An organism on the 3rd Trophic Level.
What is a tertiary consumer?
To determine parentage scientists use more than one of these.
What is an allele?
This element is "fixed" by bacteria so plants can use it.
What is nitrogen?
The two processes where the products are the same as the reactants.
What is photosynthesis and cellular respiration?
A model that shows organisms use 90% of their energy to live and grow and pass on 10% to the next level.
What is an energy pyramid?
