2Getting Energy…Organisms have to have energy- at all times- to survive.Energy comes from food.Plants use the sun to make food and energy through photosynthesis.Animals get their food and energyfrom eating other organisms.
3ProducersOrganisms that can make their own food (usually through photosynthesis).
4Consumers Organisms that cannot make their own food Consumers eat other organisms to get energy and food.There are three types of consumers:HerbivoresCarnivoresOmnivores
5Consumer 1: HERBIVORE Vegetarians (They eat vegetables and plants.) Examples:RabbitsDeerGiraffes
9*Scavengers are a type of omnivore that eats dead plants and animals. Consumer 3: OmnivoreAnimals that eat plants and animalsExamples:PigsHumansBearsRacoonsOwlsVultures**Scavengers are a type of omnivore that eats dead plants and animals.
11DecomposersOrganisms that get energy by breaking down dead organisms (including waste).They take the stored energy from the dead material, while producing simple materials, like carbon dioxide and water.Examples:FungiBacteriaEarthworms
13FOOD CHAIN!This is a model of one specific feeding relationship in an ecosystem. (A CHAIN THAT SHOWS WHO EATS WHO.)Example:Shrubs are food for deer and the deer is food for a mountain lion.So you food chain would look like this:
18Symbiosis Any close relationship between organisms There are three types of relationships:MutualismCommensalismParasitism
19This is a nice relationship. MutualismA relationship where both organisms benefit (get something good).I agree. It is lovely.This is a nice relationship.
20Mutualism ExampleFruit-eating birds will eat the fruits off of plants. The fruit is food for the bird, but the bird also spreads the plant’s seeds (by pooping them out while flying). This allows the plants to grow in different areas. Both organisms are happy!
21CommensalismA relationship where one organism benefits but the other is unaffected or doesn’t even know.I don’t even know who you are.I love our relationship!
22Commensalism ExampleHummingbirds travel from flower to flower, drinking nectar for food. Mites (small bugs) that also eat nectar, climb into the nose hole of the hummingbird and travel from flower to flower- also drinking nectar! The hummingbird doesn’t even know the mite is there. The mite benefits, but the hummingbird is unaffected.
23Ha Ha. This relationship is giving me all I need. ParasitismA relationship where one organisms benefits and the other is injured, hurt, or killed.Ha Ha. This relationship is giving me all I need.It’s killing me.Literally.
24Parasitism Example:Heartworms will live in the right side of a dog’s heart. The worms attach to the heart and grow. They will block the heart cavity and will cause death.
