Ecosystems & Communities. Organisms & the Environment. Every organism affects its environment, & in turn is affected by its environment. Remember! Communities & the environment they live in make up an ecosystem. So, ecosystems are affected by 2 types of factors:
Winds along the equator (dotted line) create currents, which are then diverted north & south. The cold, deep waters from below rise to the surface to replace these diverted waters, causing upwelling.
Tidal Zone! They can go from low tide to high tide!
What types of species do you think live in the grasslands?
What types of adaptations are necessary for living in the desert? The rainforest?
