The Necessities of Life

Every living thing needs energy in order to survive. Every time animals do something (run, jump, move) they use energy to do so. Plants don’t move, so.

The Food Chain ENERGY CONVERSION. Photosynthesis is the process that uses light energy from the sun, together with carbon dioxide and water, to make glucose.

Nature’s Recyclers The Study of Decomposers’ Cells

Decomposers  Worms, bacteria, and fungi  What role do they play in an ecosystem?

Decomposers  Organisms that eat dead organisms  Consume dead organisms and waste material

Decomposers  Important to ecosystems because of their ability to recycle important nutrients like carbon and nitrogen

Decomposers  Break down dead material that can be absorbed by plants

Nematodes  Tiny worms more commonly known as round worms  Small or microscopic

Nematodes  Contain a digestive system, mouth, pharyns, intestine, rectum and anus

Word Sorts  Algae  Plants  Producers  Phytoplankton  crayfish

Word Sorts  Zooplankton  Algae  Humans  Consumers  Bass

Word Sorts  Zebra Mussel  Carbon Dioxide  Photosynthesis  Water  Sunlight

Focus Question  What is the role of nematodes or decomposers in an ecosystem?

Hypothesis  The role of the nematode or decomposer in an ecosystem is to _________________________.

Experiment  Set up Nematode Extractor  Wait 24 hours  Look at slides under microscope  Record observations
