Biology B7

Question 1

Biodiversity

Answer 1

the variety of living organisms

Question 2

carrion

Answer 2

decaying flesh and tissue of dead animals

Question 3

community

Answer 3

made up of the populations of different species living in a habitat

Question 4

competition

Answer 4

the negative interaction between two or more organisms which require the same limited resource

Question 5

consumers

Answer 5

feed on other organisms for their energy. Can be primary, secondary or teriatry

Question 6

decomposers

Answer 6

orgaisms which feed on dead and decaying organisms. They break down on biomass and release nutrients into the soil.

Question 7

Deforestation

Answer 7

the removal and destruction of trees in forest and woodland

Question 8

Ecosystem

Answer 8

the interaction between the living organisms and the different factors if the environment

Question 9

Global warming

Answer 9

the increase of the average global temperature

Question 10

Habitat

Answer 10

where a living organism lives

Question 11

Interdependence

Answer 11

The interaction between two or more orgaisms , where it is mutually beneficial

Question 12

Population

Answer 12

the number of inividual organisms of a single species living in a habitat

Question 13

predators

Answer 13

organisms which kill for food

Question 14

Prey

Answer 14

the animals which are eaten by the predators

Question 15

Producers

Answer 15

convert the sun’s energy into useful compounds through photosynthesi. They are green plants or algae.

Question 16

scavengers

Answer 16

Organisms which feed on dead animals (carrion)

Question 17

species

Answer 17

organisms of similar morphology which can interbreed to produce fertile offspring

Question 18

What is an abiotic factor?

Answer 18

Abiotic factors are the non- living factors of an environment e.g. moisture, light, temperature, CO (small 2), wind, O (small 2) or pH

Question 19

What is biotic factors?

Answer 19

the living factors of an environment e.g. predators, competition, pathogens, availability of food

Question 20

what are adaptations?

Answer 20

They are specific features of an organism which enable them to survive in the conditions of their habitat

Question 21

what are the 3 types of adaptations?

Answer 21

• structual
• behavioural
• functional

Question 22

what is a structural adaption?

Answer 22

they are features of the organism’s body e.g. colour for camouflage

Question 23

what is a behavourial adaptation?

Answer 23

they are how the organism behaves e.g. migration to a warmer climate during colder seasons

Question 24

what are functinal adaptations?

Answer 24

they are the ways the physiological processes work in the organism e.g. lower metabolism during hibernation to preserve energy

Question 26

will an animal physically change to adapt in an environment in its lifetime?

Answer 26

No, there is a natural variation within the species and only organisms whose features are more advantageous in the environment survive. the survivors then go on to reproduce and
