Flashcards in Ecosystems Deck (32):
1

First order consumer

In a food chain, the position of a herbivore

2

Second order consumer

The animal feeding on the first order consumer

3

Third order consumer

The animal feeding on the second order consumer

4

Herbivore

A plant eating animal

5

Carnivore

An animal that feeds on other animals

6

Omnivore

An animal that eats on plants and animals

7

Photosynthesis

The process by which plants make their food

8

Word equation for photosynthesis

Carbon dioxide + water (sunlight & chlorophyll) produces glucose + oxygen

9

Biotic factors

A living factor of the environment

10

What are the 5 biotic factors

Competition
Predation
Mutualism
Parasitism
Commensalism

11

Abiotic factors

A non living factor of the environment

12

What are the 6 abiotic factors

Water
Temperature
Fire
Light
Soil type
Gas levels

13

Competition

When 2 or more organisms rely on the same environmental resource

14

Predation

Behaviour of one animal feeding on another

15

Symbiosis

The close relationship of 2 dissimilar organisms

16

Mutualism

A symbiotic relationship where both organisms benefit

17

Commensalism

A symbiotic relationship where one organism benefits but is unharmed

18

Parasitism

A symbiotic relationship where one organism benefits and one is harmed

19

Decomposer

Break down dead organic matters and wastes, recycle matter for the producers to reuse they also allow matter to cycle in all ecosystems - fungi and bacteria

20

Food web

A chain of organisms and animals that all rely on each other.

Producer
1st order
2nd order
3rd order

21

Adaptations

A feature that an organism has that enables it to survive

22

Interdependence

Relationship between organisms where one
each affects the others survival

23

Ectothermic

Animals that obtain body heat from outside their body

24

Endothermic

Animals that can generate body heat internally

25

Structural adaptation

A body part that helps an organism to survive - a ghosts bat wings allows it to fly

26

Behavioural adaptations

A feature of an organisms habitat, actions or way of life that helps it - the mouse hides in a burrow in the day, helping the mouse avoid dehydration

27

Functional adaptations

A feature of the way an organisms body works - increasing heart rate is a functional adaptation

28

Consumer

Organisms that require a ready made source of food

29

Community

All the living organisms in a an ecosystem

30

Abiotic factors that impact frogs

Temperature
Natural disasters

31

Biotic factors that impact frogs

Predators
Lack of food source
Habitat destroyed

32

Energy flow in ecosystems
- how does it flow
- how is the food material available
- fact

- energy flows from one organism to another as it is eaten
- the food material available to each organism is only that which is in the body cells of the organism it eats
- there is little energy available to the organisms by the time it reaches the end of the chain
