State that a biome is a geographical region of the planet that contains
distinctive communities of flora and fauna.
State that each biome is characterised by a distinctive climate.
State that flora is the name given to the characteristic types of
plants found in the biome.
State that fauna are the characteristic types of animals found in the
biome.
State that a biome is a group of connected ecosystems.
State that biomes can be found on land and in water.
State that examples of biomes are forest, desert, grassland, tundra,
freshwater and marine.
State that the global distribution ofbiomes is influenced by abiotic
factors .
State that the abiotic factors that influence the distribution of
biomes are temperature and rainfall.
State that the population is all the organisms of one type of species in
an ecosystem
State that a community is all the plants and animals living in the
ecosystem
State that the habitat is the place where the organisms live.
State that the community and the habitat are influenced by non-living
or physical factors called abiotic factors.
State that an ecosystem is made up of one or several habitats and
the community of organisms that live there
State that there are many habitats in an ecosystem.
State examples of abiotic (non-living) factors that interact with the
community include oxygen concentration, light intensity, temperature
and pH.
State that ecosystems need plants as the source of food and oxygen.
State that ecosystems need animals to disperse seeds.
State htat a niche is the role and organism plays in an ecosystem.
State that the niche is the use the organism makes of the resources
in the ecosystem and the interactions it makes with other organisms
in the community including competition, parasitism and predation.

Give examples of the resources that organisms make use of in the
ecosystem, including light, temperature and nutrient availability.
State that biotic factors are those that have a living origin.
State that abiotic factors are those that are non-living and have a
physical origin.
State that grazing and predation are examples of biotic factors that
affect biodiversity.
State that pH and temperature are examples of abiotic factors that
affect biodiversity
State that high intensity grazing reduces biodiversity more plant
species are eaten.
State that moderate intensity grazing maintains biodiversity as it
allows the less dominant plants to survive.
State that low intensity grazing decreases biodiversity because
vigorous plant species can outcompete less dominant plant species and
hold them in check.
State that high levels of predation decrease biodiversity as more
animals are eaten.
State that moderate levels of predation maintain biodiversity.
State that low levels of predation reduce biodiversity because more
dominant animals outcompete less dominant animals.
State that acid rain damages plant leaves and indirectly reduces plant
biodiversity.
State that acid rain decreases the pH of freshwater and kills fish.
State that acid rain may reduce biodiversity, indirectly as it can
reduce the body weight of the fish, making them less able to compete.
State that an increase in temperature can reduce biodiversity, as fish
enzymes do not work optimally.
State that an increase in temperature can reduce fish biodiversity
due to a lack of oxygen in the water.
State that exploitation means to remove resources from an
ecosystem.
State that over-hunting, over-fishing and over-grazing are ways that
humans exploit the ecosystem.
State that over-exploitation has reduced biodiversity.
State that humans have caused habitat destruction, which has
reduced biodiversity.

State that North American signal crayfish is an introduced species
that has caused the native species of white-clawed crayfish to
become endangered.
Sate that Japanese knotweed is an introduced species that
outcompetes native species.
State that pollution is anything that is added to the ecosystem that
causes harm.
State that air and water can become polluted and biodiversity is
reduced as a result.
State that lichens are indicator species.
State that lichens indicate air pollution due to sulphur dioxide.
