2. Four Laws of Ecology: Everything is connected to everything else. Everything must go somewhere. Nature knows best. There is no such thing as a free lunch.

3. All organisms fit into a: Habitat - the physical area in which an organism lives. Niche - the way of life of an organism.

4. Energy enters an ecosystem from the sun and flows between organisms as one eats another.

5. the flow of the flow of energy through energy through an ecosystem. an ecosystem. Energy is always lost from one level to the next.

6. organisms using solar or chemical energy to produce all the organic nutrients for an ecosystem.

7. Organisms that cannot make their own food. They get energy from the chemical bonds in the nutrients they eat.

8. eat primary producers (plants).

9. eat primary consumers (herbivores)

10. eat secondary consumers (carnivores)

11. eat only producers (plants)

12. eat only meat. (secondary consumers and above)

13. eat both plants and animals

14. Break down dead tissue and waste

15. So how do all of these pieces fit together????

16. the specific sequence in which organisms obtain energy within an ecosystem. SunGrassRabbitFoxBear EnergyProducerPrimary Consumer Secondary Consumer Tertiary Consumer For more information about food chains click here

17. Interrelated food chains within an ecosystem. As the diagram indicates, a food web may have many linked food chains and be very complex.

19. Within any ecosystem, some organisms utilize resources and reduce the availability of those resources to other organisms.

20. The relationship between a predator and its prey. The relationship between a predator and its prey. Even predator and prey populations are related. If the predator population is low, the numbers of the prey species will increase. Most predator species will reproduce in larger numbers if food is abundant. As the numbers of the predator species increase, the prey population begins to decline.

21. Everything is connected to everything else. Everything must go somewhere. Nature knows best. There is no such thing as a free lunch. So…to sum things up! The Four Laws of Ecology are:
