Question 1

Ecology

Answer 1

The branch of biology dealing with the relations and interactions between organisms and their enviorment, including the other organisms

Question 2

Habitat

Answer 2

Where a species lives

Question 3

Niche

Answer 3

How a species works or fits into the ecosystem. This would include the environmental conditions within which the organism can survive, grow and or reproduce; the resources the organism needs and uses; and the ways that the organisms interacts with other organisms.

Question 4

Species

Answer 4

Organisms that can breed together and produce fertile offspring

Question 5

Population

Answer 5

Is all of the organism of one type of species in an area

Question 6

Community

Answer 6

Is all of the interaction organisms in an area. It does not include the abiotic factors.

Question 7

Biotic factors

Answer 7

Living components of an ecosystem. This could include the interactions between species

Question 8

Abiotic factors

Answer 8

All of the nonliving components of an ecosystem. This could include the ph in the water, the air, the rocks, and water current

Question 9

Ecosystem

Answer 9

System by the interactions of a community of organisms and their interactions with the abiotic environment in a particular area.

Question 10

Biome

Answer 10

Large area that has a particular climate and particular species of plants and animals that live there

Question 11

Biodiversity

Answer 11

All of the living things in a particular area or region. Includes the number of different kinds of species and the relative abundance of each kind of species in an area.

Question 12

Photosynthesis

Answer 12

The process of using the energy from the sunlight, the water, and carbon dioxide and converting it into glucose which the plants use for energy. In the process they also release Oxygen.

Question 13

Autotrophs

Answer 13

Also known as self-feeders, make their own food, using simple molecules.
Two Types:
Photoautotrophs: use energy from sunlight to make organic compounds (sugars) out of carbon dioxide in photosynthesis. (Algae, Cyanobacteria)
Chemoautotrophs: use energy from chemicals to build organic compounds out of carbon dioxide or similar molecules. This is called chemosynthesis.

Question 14

Heterotrophs

Answer 14

The other-feeders, can not capture light or chemical energy to make their own food out of carbon dioxide. Humans are heterotrophs. They get organic molecules by eating other organisms.

Question 15

Herbivores

Answer 15

Organisms that are only autotrophs. Plant-eaters. Known as primary consumers.

Question 16

Carnivores

Answer 16

Organisms that eat other consumers. Meat eaters

Question 17

Omnivore

Answer 17

Organisms that eat other consumers and producers. Both plant and meat eaters

Question 18

Detritivore / decomposers

Answer 18

These organisms break down dead organic matter and wastes and use it as energy. They also break down dead waste into recycle able energy that is inserted into the soil for autotrophs to use

Question 19

Competition

Answer 19

Organisms that consume other things and cannot make their own food, will have to compete with other organisms in their same species, to achieve their food. Furthermore other species may be attracted to same prey as them, which means they will have to compete with them as well.

Question 20

Predation

Answer 20

When one organism is the prey of the other organism which is the predator. If the prey population increases the predator population increases as well. But, if the predator population increases to much, they will start to die out because there will be to much predators and the prey die off.

Question 21

Parasitism

Answer 21

One organism benefits and the other is harmed. An example could be parasites or weeds. They both suck out their nutrients and food from a particular organism. While organisms like parasites benefit, the host is harmed.

Question 22

Mutualism

Answer 22

Both organisms involved benefit. An example could be the acacia tree and ant. Both of them benefit off each other. The acacia ant lives within the tree as a space for protection. The acacia tree uses the ants to defend itself against other trees trying to live near them. The ants also scares off predators who try and eat the tree.

Question 23

Commensalism

Answer 23

One organism benefits while the other is nether harmed or helped. An exmple could be barnacles. They can live on whales or ships. They neither harm or help the whale but they do benefit by catching nutrious waves.
