Ecosystem Definition: A system formed by the interaction of a community of organisms with their natural environment. Includes biotic, or “living” components. Includes abiotic, or “non-living” components.

Ecosystem Model

Slide 4 -

Organisms in an Ecosystem Autotrophs: An organism that can make or synthesize its own food from sunlight or chemical energy.

Slide 5 -

Organisms in an Ecosystem Autotrophs: An organism that can make or synthesize its own food from sunlight or chemical energy. Heterotrophs: An organism that cannot synthesize its own food energy, and must get it from organic sources in the ecosystem in which it lives.

Slide 14 -

Different Levels of a Landscape Organisms live together in many different levels with different classifications.

Slide 15 -

Different Levels of a Landscape Species: An organism that creates a viable, fertile offspring through the process of reproduction.

Slide 16 -

Different Levels of a Landscape Population: A group of organisms of the same species living at the same place at the same time.

Slide 17 -

Different Levels of a Landscape Community: A group of interdependent species interacting with each other in the same habitat.

Slide 18 -

Different Levels of a Landscape Habitat: The geographic place and conditions in which a population and biological community exist.

Different Levels of a Landscape Day 3

Slide 20 -

Roles in a habitat Organisms need to satisfy all of their needs for life within their habitats

Slide 21 -

Roles in a habitat And sometimes try to use the same resources to live…

Slide 22 -

Roles in a habitat Definition: Competition- interaction between individuals or populations that usually has a negative effect for all organisms.

Slide 23 -

Roles in a habitat Definition: Niche - The specific area an organism inhabits - The role or function of an organism or species in an ecosystem. - The interaction of all biotic and abiotic factors relating to it.

Slide 24 -

Roles in a habitat Definition: Niche… or… An organism’s role, or “job” within the habitat and ecosystem.

Slide 25 -

Types of Niches in a Habitat Producer: an autotrophic organism that uses the process of photosynthesis to create a chemical food source.

Slide 26 -

Types of Niches in a Habitat Consumer: - a heterotrophic organism that obtains food and energy from other organisms.

Slide 27 -

Types of Niches in a Habitat Decomposer: - an organism who performs the task of recycling nutrients back into the ecosystem through the process of decomposition, as it feeds on dead or decaying organisms.

Food Chains Day 4

Slide 31 -

Food Chains Organisms can be organized into a connected line of telling where they get their energy from. This connected line is called a “Food Chain”

Slide 32 -

Food Chains We already discussed that producers are autotrophs that get their energy from the sun thru photosynthesis. Producers are called “Primary Producers” in a food chain. (write these terms down). sun Autotroph “Primary Producer”

Slide 33 -

Food Chains A heterotroph that eats the primary producer is called a “Primary Consumer. “ sun Autotroph “Primary Producer” Heterotroph “Primary Consumer”

Slide 34 -

Food Chains Sometimes heterotrophs will prey on and eat a primary consumer. They are called “Tertiary Consumers.” sun Autotroph “Primary Producer” Heterotroph “Primary Consumer” Heterotroph “Tertiary Consumer”

Slide 35 -

Food Chains Definitions: Predator: an animal that hunts and kills an animal of prey. Prey: an animal that a predator feeds upon. sun Autotroph “Primary Producer” Heterotroph “Primary Consumer” Heterotroph “Tertiary Consumer”

Slide 36 -

Food Chains If an animal is at the top of its food chain, and is not prey for another species, then it is called the “Apex Predator.” sun Autotroph “Primary Producer” Heterotroph “Primary Consumer” Heterotroph “Tertiary Consumer”

Slide 37 -

Food Chains Eventually all animals die, and their tissues are broken down by decomposers. sun Autotroph “Primary Producer” Heterotroph “Primary Consumer” Heterotroph “Tertiary Consumer” decomposer

Slide 38 -

Food Chains Sometimes an animal will eat another organism, but only after it is dead, or has been killed by a different species. These animals are called “Scavengers.” sun Autotroph “Primary Producer” Heterotroph “Primary Consumer” Heterotroph “Tertiary Consumer” decomposer

Slide 39 -

Food Chains Definition: Scavenger: an animal that eats the carcass of a dead animal it usually did not kill. sun Autotroph “Primary Producer” Heterotroph “Primary Consumer” Heterotroph “Tertiary Consumer” decomposer Scavenger.

Slide 40 -

Other Useful Definitions… Herbivore: An animal that eats only plants. Carnivore: An animal that eats only animals. Omnivore: An animal that eats both plants and animals.

Slide 41 -

Make your Own!! Your task: Use the information you have gathered about your animal to sketch a complete food chain of your animal, including the sun, primary producers, consumers (all of them) and decomposers. If your animal is prey, then draw what the predator is.

Slide 42 -

Other Useful Definitions… Label the sketch with the vocabulary words we just wrote down. Use color and make it a good quality sketch.
