This is the study of air, water, and land surrounding an organism or community
What is Environmental Science?
This is one of the steps in a food chain, web, or pyramid
What is a Trophic Level?
This nutrient comes primarily from gases in the air and is abbreviated by the letter C
What is the Carbon Cycle?
This is a community of organisms and their abiotic environment
What is an Ecosystem?
This phylum of flowering plants produces seeds within a fruit
What is an Angiosperm?
This is the condition in which human needs are met in such a way that a human population can survive indefinitely.
What is Sustainability?
An organism that has to eat other organisms to obtain energy
What is a Consumer?
This nutrient requires bacteria to fix it into the soil.
What is Nitrogen?
This is an environmental factor that is associated with or results from the activities of non-living organisms
What is an Abiotic Factor?
In an experiment, this group serves as a standard for comparison with another group
What is a Control Group?
This is a woody vascular plant whose seeds are not enclosed in an ovary or fruit
What is a Gymnosperm?
This is an organism that can make its own food and serves as the basic food source in a food chain, web, or pyramid.
What is a Producer?
This is the process by which nutrients circulate through the air, soil, water, plants, and animals in an ecosystem
What is a Nutrient Cycle?
This organism feeds by breaking down organic matter from dead organisms in an ecosystem
What is a decomposer?
This field of science studies the interactions of living organisms with one another and with their environment
What is Ecology?
An environmental factor that is associated with or results from the activities of living organisms
What is a Biotic Factor?
A diagram that shows the feeding relationships between organisms in an ecosystem
What is a Food Web?
The nutrient in this cycle is helpful to angiosperms in flower.
What is Phosphorus?
Nutrients required in large amounts within an ecosystem
What are Macronutrients?
This is why all life on Earth is confined to a relatively small layer of the atmosphere
What is the need for solar energy to drive all food chains, webs, and pyramids?
In an experiment, the group that is identical to a baseline group except for one factor
What is the Experimental Group
This principle states that the increasing concentration of toxins, like pesticides or heavy metals, in organisms at successively higher levels of a food chain, meaning top predators end up with the most dangerous levels of pollutants
What is Biomagnification?
The nutrient in this cycle is known chemically by the letter K
What is Potassium?
Producers play this role in an ecosystem.
What is changing solar energy into food that other animals can eat?
This process promotes the reproduction of organisms in a controlled manner to create better genetic lines.
What is Articicial Selection?
