Which organisms would be affected if there was a low population of rabbits? Why? ____________________________________________________________________________________________________________ 2. What would happen if there was a high population of lizards? ____________________________________________________________________________________________________________ 3.

  2. Food Chains and Webs FOOD CHAINS FOLLOW A SINGLE PATH AS ANIMALS EAT EACH OTHER. EXAMPLE: THE SUN provides food for GRASS The GRASS is eaten by a GRASSHOPPER The GRASSHOPPER is eaten by a FROG The FROG is eaten by a SNAKE The SNAKE is eaten by a HAWK. _________________________________________ FOOD WEBS SHOW HOW PLANTS & ANIMALS ARE INTERCONNECTED BY DIFFERENT PATHS. EXAMPLE:TREES produce ACORNS which act as food for many MICE and INSECTS. Because there are many MICE, WEASELS and SNAKES have food. The insects and the acorns also attract BIRDS, SKUNKS, and OPOSSUMS. With the SKUNKS, OPPOSUMS, WEASELS and MICE around, HAWKS, FOXES, and OWLS can find food. They are all connected! Like a spiders web, if one part is removed, it can affect the whole web. FOOD WEBS show how plants and animals are connected in many ways to help them all survive. FOOD CHAINS follow just one path of energy as animals find food. 1. What would happen in there was no grass in this food chain? ______________________________________________________ 2. Using the food web below, what are the two producers that the deer eats? ___________________________ 3. Why do you think the owl eats many different types of organisms? ____________________________________________________________________________________________________________
