3 Types of Consumers herbivores
4 herbivore us vegetation to swallow or devour
5 Types of Consumers herbivores the organisms that eat plants carnivores
6 carnivore us flesh to swallow or devour
7 Types of Consumers herbivores the organisms that eat plants carnivores the organisms that eat other animals omnivores
8 omnivore us all to swallow or devour
9 Types of Consumers herbivores the organisms that eat plants carnivores the organisms that eat other animals omnivores the organisms that eat both plants and animals
10 carnivore producer herbivore
11 food chain a diagram that shows the passing of materials and energy from one organism to another
12 Decomposer Organism an organism that breaks down dead organisms and returns this material to the soil bacteria and fungi
13 food web a method of illustrating the interrelationships between food chains
14
15
16 ecological pyramid illustrates energy relationships in food chains
17 carnivores herbivores producers
18 hawk carnivores 1 10 snake herbivores mouse 100 producers 1,000 units corn corn mouse snake hawk
19 biomass the dried mass of the living matter in a given area of the habitat
20 Problems with Ecological Pyramids omnivores
21 hawk snake snake mouse mouse grasshopper corn corn
22 Problems with Ecological Pyramids omnivores the eating habits of carnivores
23 polar bear polar bear seal fish fish plankton plankton
24 Problems with Ecological Pyramids omnivores the eating habits of carnivores the movement of organisms from one ecosystem to another
25 Relationships Between Organisms of the Same Species
26 Independent Organisms organisms that exist without the aid of other members of the same species examples: plants spiders bears
27 Mating for Life occurs when an animal stays with a reproductive partner until one of the pair dies examples: birds
28 Mating for Life occurs when an animal stays with a reproductive partner until one of the pair dies examples: birds fish beavers
29 Animal Societies a group of animals from the same species living together provide a means of defense
30 Animal Societies a group of animals from the same species living together provide a means of defense aid in securing food
31 Animal Societies a group of animals from the same species living together provide a means of defense aid in securing food provide instruction
32 Social Insects include ants, termites, wasps, and bees form colonies exhibit a division of labor
33 competition the struggle between organisms for an essential factor that is in short supply in the environment
34 Competition food water soil nutrients sunlight a mate
35 Competition a territory
36 Competition a territory dominance chickens pecking order wolves alpha male
37 Relationships Between Different Species competition occurs when two or more populations have the same requirements predator/prey relationships
38 predator an animal that feeds on other animals prey the animal a predator eats
39 Predator/Prey Relationships Predators are larger than prey. Predator/prey relationships keep populations within an ecosystem balanced.
40 lion zebra grass
41 Relationships Between Different Species competition predator/prey relationships parasite/host relationships
42 parasite an organism that obtains nourishment from and harms (but usually does not kill) another organism
43 host an organism that provides nourishment for and is harmed (but usually not killed) by another organism
44 Parasites are smaller than the host.
45 Almost every known living organism has parasites.
46 Parasites can live both inside and outside of a host.
47 Relationships Between Different Species commensalism mutualism
48 commensalism a relationship between two populations that benefits one and does not hurt or help the other
49 commensalism together table
50 Benefits of Commensalism food
51 scavenger an animal that eats dead animals that it did not kill itself
52 Benefits of Commensalism food housing
53 epiphyte upon plant
54 epiphyte a plant that grows on the outside of another plant but does not take nourishment from the plant on which it grows
55 mutualism a relationship between two populations that is beneficial to both
56 Obligatory Mutualism both organisms must live together or they will die examples termites and protozoans lichens
57 Nonobligatory Mutualism the organisms could survive on their own but benefit by living together examples ants and aphids cleaner fish
