Where an animal/plant species live

Question 3

Define

Community

Answer 3

A lot of the same animals/ plants in the same place

Question 4

Define

Biodiversity

Answer 4

A lot of different communities in one place.The more diverse the communities, the higher the biodiversity

Answer 5

Yes

The jungle may be small but it has more communities in it

Question 6

• Food
• Territory
• Water
• Mates

Answer 10

4

Question 11

What is the difference between

Biotic and Abiotic

Answer 11

• Biotic: Living factors(Eg: Another predator eats too many prey)
• Abiotic: Non-living factors(Eg: A flood kills of many of the animals in the community , weakening them)

Question 12

Define

Variants

Answer 12

Individuals that are similar but not the same, they be caused by genetics(during fertilisation), environment, or both.

Define

Variantation

Answer 13

Different charastics between organisms

Question 14

Countionous and Non-countionous

Answer 14

• Continuous:Numeric Variantations (Eg: Height)
• Non-continuous:Categoric Variantation(Eg: Eye colour)

(yes different heightened animals are variants, we just don’t call it out)

Question 15

What is the difference between

Inherited and Enviromental variantations?

Answer 15

• Inherited:Charateristics given to an organism by their parent organism(s)
• Enviromental:Characteristics given to an organsim, based on it’s enviroment, and where it lives.

Answer 25

• Sturctual:Adaptations to do with a physical part of the organism body
• Behavioural:Adaptations to do with the organism behaviour
• Physicological:Adaptation to do with the organism chosing to perform a process/mutation in order to survive
