We could do it on biotic or abiotic things. Among other things, we could measure the productivity of the creek or compare the different kind of algae that grow on the bottom. The three of us couldn't decided on a topic for almost a week, so we went down to the creek in the hope that it would give us some ideas. So that's what our research project is about. We wanted to know if the type of plants and the abundance of them would vary the further away they grew from the water.
Grasses are essential to the environment.
They are the source of principle food for humans and animals. They are a big link in the base of the food chain. They are too hard to tell apart. Although some may look the same, at closer inspection, each type of grass has it's own unique characteristics. Grasses grow everywhere in the world, from the Arctic Circle into the jungles near the equator.
