Flashcards in Unit 1: Ecology Vocab Deck (48):
1

Non-living things

Abiotic

2

Organisms that get their energy from nonliving resources, meaning they make their own food

Autotroph

3

The wide array and assortment of species that are found in any ecosystem

Biodiversity

4

Living things (and things that were living)

Biotic

5

Cycle in which carbon continually flows from the environment to living organisms

Carbon Cycle

6

The maximum number of individuals of a particular species that an environment can normally and consistently support

Carrying Capacity

7

A relationship between two species in which one receives an ecological benefit from another, while the other neither benefits nor is harmed

Commensalism

8

A group of different species that live together in one area

Community

9

Ecological relationship that occurs when two organisms fight for the same limited resource

Competition

10

Limiting factors that are affected by the number of individuals in a given area

Density-Dependent Limiting Factor

11

Aspects of the environment that limit a population's growth regardless of the density of the population

Density-Independent Limiting Factor

12

Constantly changing balance

Dynamic Equilibrium

13

A temporary change in environmental (biotic or abiotic) conditions that causes a pronounced change in an ecosystem

Ecological Disturbance

14

The variety of habitats that occur within a region

Ecological Diversity

15

The process of assisting the recovery of an ecosystem that has been degraded, damaged, or destroyed

Ecological Restoration

16

A community of organisms (all of the organisms living in a specific area) and their abiotic environment

Ecosystem

17

The ability of an ecosystem to recover from a disturbance

Ecosystem Resilience

18

The ability of an ecosystem to remain relatively unchanged when subjected to a disturbance

Ecosystem Resistance

19

A species that is in danger of becoming extinct

Endangered Species

20

Population growth that occurs when a population size increases dramatically over a period of time

Exponential Growth

21

A natural fuel, such as oil, coal, or gas formed in the geological past from the remains of living organisms

Fossil Fuel

22

The combination of different genes found within a population of a single species

Genetic Diversity

23

The warming of the surface and lower atmosphere of Earth that occurs when carbon dioxide, water vapor, and other gases in the air absorb and re-radiate infrared radiation

Greenhouse Effect

24

Gasses such as water vapor, carbon dioxide, and methane contribute to the greenhouse effect

Greenhouse Gasses

25

PRocess by which part of an organism's preferred habitat range becomes inaccessible

Habitat Fragmentation

26

Organisms that get their energy by eating other living or once-living resources such as plants and animals

Heterotroph

27

The term for maintaining a constantly changing balance in a living organisms or other living system

Homeostasis

28

Mutual dependence between things (e.g. living things depend on each other for survival)

Interdependence

29

A species that is not native and was brought to an area as a result of human activities

Introduced Species

30

Environmental factor that limits the growth and size of a population

Limiting Factor

31

Population growth that occurs when a population grows rapidly at first then slows down and levels off at the carry compacity

Logistic Growth

32

A relationship between two species in which both species benefit from one another

Mutualism

33

Things (such as various chemical compounds like sugars) that come from living organisms

Organic

34

A relationship between two species in which one species, that parasite benefits from the other species, the host, which is harmed

Parasitism

35

Process where plants use energy from the sun to convert carbon dioxide from th atmosphere into organic material that becomes part of the plant

Photosynthesis

36

An undesirable change in the natural environment that is caused by the introduction of substances that are harmful to living organisms

Pollution

37

A group of the same species that live in one area

Population

39

Rain, snow, sleet, or hail that falls to the ground

Precipitation

40

The process by which one organisms, the predator, captures and feeds upon another organism, the prey

Predation

41

Establishment and development of an ecosystem in an area that was previoulsy uninhabited

Primary Succession

42

Process where living things break down organic material for energy and release carbon dioxide back into the atmosphere

Respiration

43

Reestablishment of a damaged ecosystem in an area where soil was left intact

Secondary Succession

44

A group of organisms that are closely related and can mate to produce fertile offspring
