Biology Ecosystems

Objective Organisms cooperate and compete in ecosystems

Ecology

The study of ecosystems Ecology The study of ecosystems

Ecosystems include all the interacting parts of the environment in an area.

A niche is the sum total of an organism's use of biotic and abiotic resources in the environment, how it "fits into" an ecosystem.

A number of different animals can live in the same biome because each occupies its own special space, or niche.

A niche may apply to species, populations, or even individuals

Species cannot coexist in a community if their niches are identical.

After years of searching Walter finally found his niche.

Habitat The physical area in which an organism lives.

Niche The way of life of an organism.

Prey Predator Predator's predator Predation

Refers to the relationship between a predator and prey. Predator's predator Refers to the relationship between a predator and prey. Predation

In other words, one organism using another for food. Prey Predator Predator's predator In other words, one organism using another for food. Predation

Carnivores Herbivores Omnivores eat only meat eat only plants eat plants and meat

Food Chain: The specific sequence in which organisms obtain energy within an ecosystem.

Also called herbivores, Primary Consumers Also called herbivores, eat only plants.

Also called carnivores, Secondary Consumers Also called carnivores, eat only animals.

Tertiary Consumers eat secondary consumers.

Food Web

Interrelated food chains within an ecosystem. Food Web Interrelated food chains within an ecosystem.

Why don't humans eat carnivores?

Trophic is a word associated with energy. Food Pyramid Kingfisher Trout Insect Larvae Algae Food Pyramid

Kingfisher Trout Insect Larvae Producers 100% Algae

All producers are able to make their own food through photosynthesis. Kingfisher Trout Insect Larvae Producers 100% Algae

Food stored by producers is ALL the food energy available in the food chain. Kingfisher Trout Insect Larvae Producers 100% Algae

Primary Consumers 10% Producers 100% Kingfisher Trout Primary Consumers 10% Insect Larvae Producers 100% Algae

Primary consumers feed on producers. Primary Consumers 10% Kingfisher Trout Primary Consumers 10% Insect Larvae Producers 100% Algae

Primary consumers use 90% of their food energy to stay alive. Kingfisher Trout Primary Consumers 10% Insect Larvae Producers 100% Algae

Secondary Consumers 1% Primary Consumers 10% Producers 100% Kingfisher Secondary Consumers 1% Trout Primary Consumers 10% Insect Larvae Producers 100% Algae

Tertiary Consumers 0.1% Secondary Consumers 1% Primary Consumers 10% Kingfisher Secondary Consumers 1% Trout Primary Consumers 10% Insect Larvae Producers 100% Algae

Only 10% of the energy in one trophic level is available as Tertiary Consumers 0.1% Kingfisher Only 10% of the energy in one trophic level is available as food for the next higher level. Secondary Consumers 1% Trout Primary Consumers 10% Insect Larvae Producers 100% Algae

ALL food chains, food webs, and food pyramids begin with producers. Algae

A normal food pyramid looks like this.

Give me an example of how the pyramid could look like this.

Protective Coloration

Protective Coloration Allows an organism to blend with the environment. Protective Coloration

A prey animal looks like a dangerous, or bad tasting, animal. Mimicry

Symbiosis is a close association between two dissimilar organisms.

One organism benefits (parasite), the other is harmed (host). http://wps.prenhall.com/wps/media/objects/489/501279/CDA49_1/CDA49_1a/CDA49_1a.htm Parasitism One organism benefits (parasite), the other is harmed (host).

One organism benefits, the other neither benefits or is harmed. Commensalism One organism benefits, the other neither benefits or is harmed.

Both organisms benefit equally. Mutualism Both organisms benefit equally.

Mutualism is common in nature.
