Ecosystems Test 2
- Ecosystems
- All living and nonliving things in that area
- Interacting together
- Ecology
- Study of how these things interact in order to survive
- Abiotic Factors
- Nonliving things needed to survive
- Water, minerals, sunlight, air, climate, and soil
- Biotic Factors
- Living parts of the ecosystem
- Animals, plants, fungi, protist, bacteria
- Prairies
- Soil
- Rich dark soil
ii. climate- precipitation and weather
summer- dryhot
fall- dry cool
winter- snow cold
springrain warm
- Consumers
- Something that consumes(eats) plants or animals
- Mustang, tiger, mountain lion
- Gives off carbon dioxide to plants
- Producers
- Something that produces(makes) food for animals to live
- produces oxygen
- shrubs, grasses, trees
- Desert
- Soil
- Sand
- Often rich in minerals
- Poor in animal and plant decay
ii. climate precipitation and weather
summer dry hot
fall don’t have
winter don’t have
springdon’t have
- Consumers
- Lizards, snakes, owls, scorpions
- Producers
- Cactus, cattail, shrubs, yuccas
- Freshwater
- Soil
- Water
- Bottom would include:
- Sand, dirt
ii. climate
based on ecosystem they are in
- Consumers
- Cat fish, painted turtle, salmon
- Producers
- Seaweed lily pads, moss
- Plankton
- Organisms float on water
- Nekton
- Organisms swim through water
- Benthos
- Bottom-dwelling organisms
- Saltwater
- Soil
- Salt water
ii. climate
based on ecosystem they are in
- Consumers
- Sharks, clown fish, dolphin
- Producers
- Coral, seaweed,
- Rain forests
- Soil
- Nutrient poor
ii. climate
summer rain hot
fall rain warm

- Consumers
- Animals that consume or eat plants or other animals
- Tiger, tree frog, monkey
- Give off carbon dioxide to plants so they can make food
- Producers
- Orchids, ferns, vines
- Plants & algae that produce oxygen & food animals need
- Consumers and producers balance out an environment
- Decomposers
- Fungi and bacteria break down dead plants & animals into minerals that enrich the soil
- Ends the food chain
- Worms, insects, bacteria, fungi
- Population
- All organisms living in the same area
- Organism
- All living things that carry out its life on its own
- Community
- All the different populations living in an area and how they interact
- Prey
- It is what an animal eats
- Mice eat insects
- Coyote eats sheep
- Predator
- What eats that animal
- Deer gets eaten by humans
- Rabbit gets eaten by coyote, hawks, wolf
- Ecosystem thrown off balance when a new predator enters
- Or prey leaves
- Variables that affect ecosystems
- Humans, birth rate, climate
- Habitat
- Place where an organism lives
- Frog lives in a pond
- Bat lives in the tree
- Monkey lives in a rainforest
- Niche
- Role of an organism in the community
- What the animal eats
- What eats that animal
- Environment needed to live in
- Active by day or by night
- Food Chain
- Path of energy in food from one organism to another
- Starts with the sun to a seed
- Then goes to a plant- mouse
- Then to a prey- cat
- Then to a predator-coyote
- Finally to a decomposer
- Food Web
- Shows relationship between all of the species of a community
- Map of overlapping food chains
- Snakes, deer, trees, rabbits, mice, insects, birds, fungi, hawks, mountain lions, grass,
- Herbivores
- Only eat plants (producers)
- Carnivores
- Animals that eat other animals
- Omnivores
- Eat both animals (consumers)
- And plants (producers)
Vi. Scavengers
- Eat meat but don’t hunt it
- Rely on dead animals
- Such as vultures, crows, hag fish
- Adaptations
- Characteristics that help an organism survive in its environment
- cactuses
