45 Terms

1

DDT

synthetic pesticide used to control insects. DDT was used to battle malaria Its effects include thinning of eggshells, bioaccumulation in food chains, and potential harm to wildlife and humans.

New cards
2

ecocentrist

places nature and the environment at the center of their values and decision-making, prioritizing ecological well-being over human interests.

New cards
3

technocentrist

believes in the central role of technology in society, often prioritizing technological solutions over other factors. Environmental issues can be solved by development (e.g. trump)

New cards
4

A silent spring

New cards
5

Niche

how an organism makes a living

New cards
6

ecoystem

where plants, animals and other organisms as well as weather work together to form a bubble of life

New cards
7

ecology

study of organisms and their interactions

New cards
8

habitat

environment in which a species normally lives

New cards
9

species

a group of organisms that share common characteristics, that can interbreed and create fertile offspring

New cards
10

biotic

living factors that affect an ecosystem(plants, animals, bacteria)

New cards
11

abiotic

non-living factors that affect an ecosystem(weather, humidity, soil, proximity to water)

New cards
12

carrying capacity

the maximum population that an environment can sustainably support

New cards
13

population density

average amount of organisms within an area (e.g. m²)

New cards
14

population

a group of organisms of the same species living in the same area at the same time

New cards
15

Realised Niche

actual conditions and resources in which a species exists due to biotic reactions

New cards
16

fundamental niche

full range of conditions which a sepcies could live in(basic needs)

New cards
17

spatial niche partitioning

differebt species occupy different spaces in a habitat

New cards
18

dietary niche partitioning

different species eat different things

New cards
19

Niche partitioning by resource height

Species occupy same habitat but have access to resources at different heights

New cards
20

Temporal niche partitioning

species share a habitat but feed at differebt times(times of day, seasons, environmental conditions)

New cards
21

Positive Feedback

a cycle that amplifies change within an environment.

New cards
22

Negative feedback

steady-state equilibrium. Cycle that stabilizes itself and always returns to its original state

New cards
23

Limiting factors

factors that slow population growth.

New cards
24

Biotic limiting factors

Density dependent. food, competition, parasitation

New cards
25

Abiotic limiting factors

Density independent. Rainfall, sunlight, temperature

New cards
26

Autotrophs

use energy from the sun to photosynthethise and grow

New cards
27

Mutualism

two species benefit from eachother

New cards
28

Parasitism

one benefits at the expense of the other

New cards
29

Predator and prey

one feeds off of the other

New cards
30

Pathogen

causes a disease

New cards
31

decomposers

break down dead organisms

New cards
32

detritivores

feed by consuming dead matter or faeces

New cards
33
<p>system</p>

system

shows inputs, outputs and stores of an ecosystem

New cards
34

open system

can exchange both energy and matter with its surroundings

New cards
35

closed system

no matter is lost, energy can be transferred

New cards
36

isolated system

doesn’t excange matter or energy

New cards
37

daisy planet

an environmental model that shows how negative feedback loops affect the temperature of earth

New cards
38

first law of thermodynamics

energy in an isolated system cannot be created or destroyed

New cards
39

second law of thermodynamics

entropy of a system is always increasing

New cards
40

entropy

the dispersal of energy through work: evaporation, waste, respiration

New cards
41

resillience

the ability of a system to return to its initial state after a disturbance

New cards
42

bioaccumulation

build-up of chemicals in an individual organism over time

New cards
43

biomagnification

build-up of pollutants over several trophic levels, the top predator consumes the highrst concentration as they have to eat several small polluted creatures

New cards
44

primary pollutants

are emmited directly from one source

New cards
45

secondary polllutants

form in the atmospherethrough cheical reactions
