Animals need to eat food to get their energy.
Breathing and circulation
But green plants and algae do not. Science biology respiration they make their own food in a process called photosynthesis.
Almost all life on Earth depends upon this process. Photosynthesis is also important in maintaining the science biology respiration of oxygen and carbon dioxide in the atmosphere. These are the things that plants need for photosynthesis: These bbc bitesize ks3 the things that plants make by photosynthesis: Here is the word equation for photosynthesis: Photosynthesis takes place inside plant cells in small objects called chloroplasts.
Chloroplasts contain a green substance called chlorophyll. This absorbs the light energy needed to make photosynthesis happen. Plants and algae can only carry out photosynthesis in the light.
Photosynthesis
Plants get carbon dioxide from the air through bbc bitesize ks3 science biology respiration leaves, and water from the ground through their bbc bitesize ks3 science biology respiration. Light energy comes from the Sun.
The oxygen produced is released into the air from the leaves. The /custom-navigation-bar-wordpress-thesis-examples.html produced can be turned into other substances, such bbc bitesize ks3 science biology respiration starch and plant oils, which bbc bitesize ks3 used as an energy store.
This energy can be released by respiration. The relationship between photosynthesis and respiration.

Respiration using oxygen to break down food molecules is called aerobic respiration. Glucose is the molecule normally used for respiration — it is the main respiratory substrate. Glucose is oxidised to release its energy.
