prey
1. usually breed faster than predators
2. usually breed slower than predators
3. are usually larger than predators
4. are always herbivores
predators
1. usually have a smaller population than their prey
2. cannot usually run as fast as their prey
3. are always omnivores
4. usually have eyes on the side of their heads
prey
1. often have eyes on the side of their heads, for all-round vision
2. often have eyes on the front of their heads, to judge distances
3. are always omnivores
4. do not have good hearing
producers in a food chain are
1. always plants
2. always herbivores

photosynthesis
1. takes in carbon dioxide
2. takes in oxygen
3. gives off energy
4. happens in the cell vacuole
Respiration
1. happens in plants and animals
2. happens in animals
3. happens in plants
4. happens in our lungs
Respiration
1. happens in our cells
2. happens in our respiratory system
3. needs energy
4. doesn't happen in plants
Respiration is
1. a chemical process in your cells
2. the process of getting oxygen into your lungs
3. the process of getting water up a tree trunk to the leaves
4. another name for breathing
The word equation for respiration is
1. food + oxygen --> carbon dioxide + water + energy
2. food + oxygen + energy --> carbon dioxide + water
3. food + carbon dioxide --> oxygen + energy
4. food + oxygen --> carbon dioxide + energy
deciduous trees
1. lose their leaves in winter
2. keep their leaves all year round
3. have long, spine-like leaves
4. are not found in Britain
"migration" means
1. e.g. birds flying south for the winter
2. e.g. bears sleeping through the winter
3. plants storing food in underground bulbs
4. trees losing their leaves in winter
"hibernation" means
1. e.g. bears sleeping through the winter
2. e.g. birds flying south for the winter
3. plants storing food in underground bulbs
4. trees losing their leaves in winter
food webs
1. show how food chains are related
2. are the same as food chains
3. show how many animals are at each level in the food chain
4. always start with carnivores
a polar bear is white because
1. it is camouflaged against the snow
2. it reflects the sun's heat
3. it keeps body heat in a lot better
4. their fur sheds water quickly
predator populations
1. fall after their prey population falls
2. fall before their prey population falls
3. tend to be larger than their prey population
4. fall when their prey population rises
