An ecosystem is all the living and non-living things that interact in a particular area. Animals? Plants? Rocks? Oxygen? Soil? Minerals?
Organisms live within a specific place within an ecosystem. An organism obtains food, water, shelter, and other things it needs to live, grow, and reproduce from its surroundings. The place where an organism lives and provides its needs is called its habitat.
A prairie dogs habitat is in underground tunnels. A mushrooms habitat is in moist soil, tree bark, or mossy rocks.
An ecosystem may contain MANY habitats. An animal or plant lives in a particular ecosystem because it meets the organisms needs. Habitat Video
What is the difference between a habitat and an ecosystem? HOMEWORK:Pick an ecosystem and create a detailed illustration including at least 3 living items and 3 non-living items. This assignment must be colored in order to receive full credit. NO WRITING REQUIRED.
Animals interact with both living and non- living elements in the environment. The living parts of an ecosystem are called biotic factors.
Im going to call out a letter of the alphabet. You will have 45 seconds to pick a biotic factor starting with that letter. Try to be creative because if you and another student have the same answer, then youre out. Winners will receive prizes!
Include: All plants All animals Decomposers Worms, Fungi, Protists, & Bacteria
All non-living parts of an ecosystem are called abiotic factors. These factors include: Water ~ very important for photosynthesis Sunlight ~ without plants we couldnt survive Oxygen ~ animals need it to survive Temperature Soil ~ provides homes for many animals
With which abiotic factors is the frog interacting with here?
What do you already know about populations? A species is a group of organisms that are physically similar and can reproduce with each other to produce offspring. A population is all the members of one species in a particular area.
Designer Dogs AKA Goldendoodle & Morkie Dogs can be bred with one another because they are all the same species: Canis familiaris
Golden RetrieverStandard Poodle Goldendoodle HippopotamusRhinocerous
The Giant Panda is a species. Panda Facts! The Grizzly Bear is its own species.
Grizzly Bears Classification: Phylum: Chordata this means the animal has a backbone. Class: Mammalia this means the animal is a mammal Order: Carnivora this means the animal is a carnivore Family: Ursidae this means the animal is in the bear family Genus: Ursus this designates the bear as a grizzly We classify organisms in order to group them by similar characteristics. Check out these other bears…bears
If a cat is an organism within a species… My oldest cat, Lucky
All of the cats within a particular area (my house) are considered to be a population. Button
All the prairie dogs in Texas All the pigeons in New York City All the daisies in a field
All the trees in a forest Why is this not a population? The area in which a population lives can be as small as a single blade of grass or as large as the whole planet. Brainstorm other types of populations.
All of the different populations that live together in an area make up a community. Remember, ecosystems are made up of more than just one population of species. For example, a ocean ecosystem is made up of more animals than just whales.
A prairie community may include: Prairie Dogs Hawks Tall grasses Badgers Snakes Insects And more… All of these are populations on their own, but together make up a community.
