This is the scientific study of interactions among organisms and between organisms and their environment, or surroundings.
What is ecology?
100
A collection of all the organisms that live in a particular place, together with the nonliving, or physical environment is known as this.
What is an ecosystem?
100
Organisms able to capture energy directly from sunlight or inorganic chemical compounds in their environment are known as this.
What are autotrophs?
100
Organisms that obtain energy only from plants are known as this.
What are herbivores?
100
The total amount of living tissue within a given trophic level is known as this.
What is biomass?
200
This biological grouping contains combined portions of the planet in which all life exists.
What is the biosphere?
200
A group of ecosystems that have the same climate and similar dominant communities is known as this.
What is a biome?
200
Another term used to describe autotrophs and is derived from their ability to produce their own food is this.
What is producers?
200
Organisms that obtain energy only from other animal organisms are known as this.
What are carnivores?
200
A diagram that shows the relative amounts of energy or matter contained within each trophic level in a food chain or food web is known as this.
What is an ecological pyramid?
300
A group of organisms so similar to one another that they can breed and produce fertile offspring is known as this.
What is a species?
300
These are the three basic approached to modern ecological research.
What are observing, experimenting, and modeling?
300
The process in which autotrophs convert solar energy into chemical energy is known as this.
What is photosynthesis?
300
The series of steps in which organisms transfers energy is known as this.
What is a food chain?
300
As one goes up each trophic level in an ecosystem, the number of individuals in each level does this.
What is decreases?
400
Groups of individuals that belong to the same species and live in the same area are known as this.
What are populations?
400
This is the main source of energy on Earth.
What is the Sun?
400
The process in which autotrophs convert chemical energy into chemical energy is known as this.
What is chemosynthesis?
400
The complex network of feeding relationships among various organisms within an ecosystem are known as this.
What is a food web?
400
The direction of matter within and between ecosystems is this.
What is circular?
500
Assemblages of different populations that live together in a defined area are known as this.
What are communities?
500
This is an alternative source for energy for some organisms on Earth.
What are inorganic chemical compounds?
500
Organisms that rely on other organisms for energy and food are known as this.
What are heterotrophs?
500
This is the amount of energy transferred from one trophic level to the next is this.
