1. What do plants need to survive and what do they give back to the environment? 2. What is the typical cycling of matter and energy among organisms?
3. What are the 5 main elements that cycle through the ecosystem?

Hello So for your first question the answer will be: Like humans and animals, plants need both water and nutrients (food) to survive. Most all plants use water to carry moisture and nutrients back and forth between the roots and leaves. Water, as well as nutrients, is normally taken up through the roots from the soil. second answer will be: At each link in an ecosystem, matter and energy are conserved. Photosynthesis and cellular respiration are important components of the carbon cycle, in which carbon is exchanged among the biosphere, atmosphere, oceans, and geosphere through chemical, physical, geological, and biological processes. And final answer will be:Biogeochemical cycles important to living organisms include the water, carbon, nitrogen, phosphorus, and sulfur cycles. Hope that helps! :)
