Description

Presentation about Greenhouse in space

Plants are multi cellular living things. They grow, excrete, respire, reproduce and respond to external stimuli. They are our main source of food and without plants there would be no humans or animals. Can you think of reasons why? Think about food chains and food webs you have studied. What do all the food chains begin with? Draw some food chains and food webs making them as complex as you like. From these you should be able to clearly see the essential role of plants. Every food chain has at its start point, organisms that are able to produce their own food (plants and chemotrophs). On Earth we have all the ingredients necessary for life: Air, water, light, nutrients and warmth. We (and all animals) are able to get our energy to live and grow from the food we eat and the oxygen from the air.
