enzymes

• photosynthesis
• respiration
• decomposition

carbon dioxide

oxygen

• protein molecules
• they are made up of long chains of amino acids

denature

a biological catalyst that speeds up the rate of biological reactions in an organism without being used up.

• stage 1: photosynthesis
• stage 2: carbon is converted into carbs, fats & proteins for the animal
• stage 3: respiration
• stage 4: decomposition

• moisture
• warmth
• oxygen

organisms remove material from the environment for growth and other purposes. These materials are returned to the environment when the organisms die.

• less animals
• limit the movement
• control the conditions in which the animals live in

• keeping warm
• movement
• growth

greenhouses can be used to make plants grow more quickly and become bigger and stronger.

less light decreases the rate of which photosynthesis can happen

• light
• temp
• co2 conc

carbon dioxide + water --> glucose + oxygen

to make chlorophyll which gives the plant its green colour

to form proteins once added with amino acids

• mineral ions,
• sunlight,
• warmth,
• carbon dioxide

a membrane that only allows certain substances to pass through

when there is a net movement in particles

in gases and solutions

carbon dioxide
