How do you make living things easier to name and study ?
We classofy them into groups and subgroups.
1 of 11
Organisms that interbreed and produce fertile offspring are ?
members of the same species.
2 of 11
What do Food webs show ?
how energy from the sun flows through ecosystems, from producers to secondary consumers.
3 of 11
What happens to the mass of living materials ?
the biomass gets less as you move along food chains.
4 of 11
What happens to energy flows from the plants that capture it to carnivores ?
some is lost at each step as heat and in waste materials.
5 of 11
How is carbon in living things recycled ?
Photosynthesis traps carbon dioxide in biomass. It passes along food chains and is released when living things respire or decompose.
6 of 11
How is Nitrogen Recycled ?
Plants use nitratesfrom soil to build proteins which pass along food chains. Decomposers return the nirtogen to the soil as ammonia and bacteria convert this back to nitrates.
7 of 11
What do resources do living things compete for ?
Light, SPace, Water, Minerals, Carbon Dioxide, animals for food, Territory, Mates and Water.
8 of 11
What adaptations do predators and prey aid for survival ?
They change to one population have a direct effect on the other.
9 of 11
How do artic animals adapt & Desert animals ?
Artic animals are adapted to minimise heat loss and desert animals are adapted to minimise water loss.
10 of 11
What are plants adapted to do ?
Control water loss and light absorption.
