This document defines key concepts in ecology including habitat, environment, adaptation, mimicry, producers, consumers, predators, prey, herbivores, carnivores, omnivores, food chains, and food webs. It provides examples of each concept and asks the reader to name examples of producers, consumers, vertebrates, invertebrates, and to write a four organism food chain. It also asks the reader to provide examples of how humans destroy natural habitats such as overfishing, cutting down trees, pollution, and pesticide use.

1. The study of living organisms;
how they affect each other and
their surroundings.
*Ecology

*Habitat: is the place where
an organism lives.
*Environment :is the
surroundings of an organism.

7. *Predator: an animal that
hunts and eats other animals.
*Prey: an animal that is eaten
by a predator
*Herbivore: an organism that
feeds on plants.
*Carnivore: an organism that
feeds on animals.
*Omnivore :an organism that
feeds on both plants and
animals

*Producer: an organism that
can make its own food
*Consumer: an organism that
feeds on other organisms.

*Energy from the sun flows in one direction .
*Food chain: shows the feeding relationships of organisms
with arrows representing the energy flow.

12. *Food web
*Can you name:
*2 producers?
*2 consumers?
*2 vertebrates?
*2 invertebrates?
*Write down a food chain that
contains four organisms.

* Give examples of ways
humans destroy natural
habitats.
*Over fishing, using nets that are dragged on sea floor.
*Cutting down trees.
*Polluting rivers, lakes and seas.
*Using pesticides to kill pests.
