Rain Forest  #ecosys5

2. biotic/abiotic

living: howler monkey, jaguar, moss, flowers, aligators,

nonliving: rocks, dirt, air,

3. limiting factors

animals in the rain forest will pick one thing for survival (food, water, shelter) if they cant get that one thing for survival then their chances of survival will decrease. But if they are able to get that one thing for survival their chances will increase

5. predator/prey relationships

Example: a jaguar will hunt its food(prey). the predator depends on its pray to eat. if there is no food then the jaguar will have nothing to eat.

6. energy roles

the primary consumer only gets 10% of the energy so if a grasshopper eats a plant and the plant has 100% energy then the grasshopper only gets 10% of the 100% if a bird eats the grasshopper then the bird only will get 1% of the 10% from the grasshopper.

6. food web/food chain

food chains show the movement of energy flow in the direction of The arows. food webs show different animals that eat different types of animals in different areas of The world.

7.trophic levels and energy pyramids

a jaguar is at the top of the food pyramid and can eat anything below it at the bottom of a food pyramid a producer then primary consumer then secondary consumer then last but not least third consumer.

photosynthesis is how the plants get their food and give out oxygen. the sun gives the plant energy the plant takes in carbon dioxide and makes glucose to eat the gives out oxygen.

9. tropism

positive tropism moving toward                negative tropism moving away

geotropism: movement towards or away from the earth

phototropism: movement towards the sun

gravitropism: movement towards or away from gravity

thigmotropism: movement towards or away from touch

if we didn't have any decomposers our world would be covered in trash. Decomposers give nutrients to the dirt so fresh plants can grow.

animals have to adapt to there environment in order to survive    Ex: poler bear is white for camouflage in the snow

12. Natural selection
natural selection is when the baby has some receive trait instead of the dominant trait.

  1. Rain forests belong to the tropical wet climate group. The temperature in a rain forest rarely gets higher than 93 °F (34 °C) or drops below 68 °F (20 °C); average humidity is between 77 and 88%; rainfall is often more than 100 inches a year.
  2. living: howler monkey, alligator, birds, plants, moss, etc

    nonliving: rocks, air, clouds, rain, etc
