Front 1

Define ecosystem

Back 1

A biological community of interacting organisms and their physical environment.

Front 2

Define ecology

Back 2

The branch of biology that deals with the relations of organisms to one another and to their physical surroundings.

Define Biotic

Back 3

relating to or resulting from living things, especially in their ecological relations.

Define abiotic

Back 4

Non living things

Front 5

Define predation

Back 5

Is where one species eats another.

Front 6

Define Commensalism

Back 6

Where a species benefits from another species.

Front 7

Define Mutualism

Back 7

When two species benefit from each other.

Front 8

Define parasitism

Back 8

The parasite lives off of the host, harming it and possibly causing death of the host

Front 9

Define Competition

Back 9

Two different species are fighting for the same resources.

Front 10

Define producer

Back 10

A organism that serves as a source of food for other organisms in a food chain.

Front 11

Back 11

A organism that feeds on other organisms in a food chain.

Front 12

Define Decomposer

Back 12

an organism, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material.

Front 13

What's a food chain?

Back 13

A series of organisms each dependent on the next as a source of food.

food.

Front 14

What's a food web?

Back 14

a system of interlocking and interdependent food chains.

Front 15

What's population?

Back 15

In genetics a population is a group of interbreeding individuals of the same species, which is isolated from other groups.

Front 16

What's carrying capacity?

Back 16

The carrying capacity of a biological species in an environment is the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water, and other necessities available in the environment

Front 17

What's limiting factors?

Back 17

In ecology, common limiting factor resources are environmental conditions that limit the growth, abundance, or distribution of an organism or a population of organisms in an ecosystem.

Front 18

What's species diversity?

Back 18

Species diversity is the number of different species that are represented in a given community.

Front 19

What is watershed?

Back 19

an area or ridge of land that separates waters flowing to different rivers, basins, or seas.

Front 20

What is sustainability?

Back 20

refers to the capacity of the biosphere to meet the needs of the present generation, without hindering future generations from being able to meet their needs. This means using our natural resources wisely in the short-term so that these resources are available in the long-term.

Front 21

What is fragmentation?

Back 21

the process or state of breaking or being broken into small or separate parts.

Front 22

What is equilibrium?

Back 22

a state in which opposing forces or influences are balanced.

Front 23

What is biodiversity?

Back 23

the variety of life in the world or in a particular habitat or ecosystem.

Front 24

What is extripated?

Back 24

root out and destroy completely.

Front 25

What is succession?

Back 25

is the gradual process by which ecosystems change and develop over time. Nothing remains the same and habitats are constantly changing. There are two main types of succession, primary and secondary.

Front 26

Water vs. Terrestrial

Back 26

Almost all the habitats found in the world can be put into two major habitats; aquatic and terrestrial. Aquatic ecosystems are found in water .Terrestrial animals are the animals who live on land for most or all of their life span. ... Water plants do not have roots and do not have woody or stiff trunks.

Front 27

3 Key things for a ecosystem

Back 27

Producers,consumers, decomposers.

Front 28

What's the 5 Biotic interactions in an ecosystem?

Back 28

Predation,commensalism,mutualism,parasitism,competetion.

Front 29

Carbon cycle

Back 29

Front 30

Water cycle

Back 30

Front 31

Nitrogen cycle

Back 31

Front 32

Alge bloom

Back 32

Fertilizer gets washes away by heavy rain, gets into river. Causes alge to grow like wildfire and then once it has no food left, dies. As it rots it sucks air out of the water. Killing the species in the river.

Front 33

Why and how are water sheds important?

Back 33

Drains surface water and storm water to run off drain into other bodies of water.

Front 34

What is biosphere?

Back 34

the regions of the surface, atmosphere, and hydrosphere of the earth (or analogous parts of other planets) occupied by living organisms.

Front 35

What is a lithosphere?

Back 35

the rigid outer part of the earth, consisting of the crust and upper mantle.

Front 36

What is a hydrosphere?

Back 36

All the waters on the earth's surface, such as lakes and seas, and sometimes including water over the earth's surface, such as clouds.

Front 37

What is atmosphere?

Back 37

the envelope of gases surrounding the earth or another planet.
