The Organisation of an Ecosystem

how does carbon enter the atmosphere

combustion and respiration

what are the key stages of the carbon cycle

photosynthesis and respiration

what is aerobic respiration

plants and animals take in oxygen from the atmosphere and release co2

all living things respire

what is photosynthesis (carbon cycle)

plants take in co2 and release oxygen this ensures there is plenty of oxygen for respiration and helps to stop the co2 level in the atmosphere getting too high it also produces glucose, which is essential for plant growth.

what is the word equation for photosynthesis

carbon dioxide + water = glucose + oxygen (with the help of light and chlorophyll)

what factors affect the rate of photosynthesis

sunlight, carbon dioxide concentration, temperature, water availability. and chlorophyll

what does the chlorophyll do

it gives colour to the leaves and it absorbs sunlight and uses its energy to convert carbon dioxide and water into glucose

how do plants use glucose

glucose is a carbohydrate plants use it to increase their biomass which mean iff they are increasing their biomass what are they doing they are growing there faster the rate of photosynthesis the quicker the sugar is formed and the faster the plant grows most plants convert glucose into starch.
