Welcome to 7th grade Science
We are now beginning our unit on the Ecosystem.
We will cover 7.12 a-diagram the flow of energy within trophic levels and describe how the available energy decreases in successive trophic levels in energy pyramids. and
7.12 b--describe how ecosystems are sustained by the continuous flow of energy and the recycling of matter and nutrients within the biosphere.
Students with analyze food webs, create food chains and energy pyramids. They will also calculate the amount of energy that will be passed along each trophic level.
