Summary #7

Places to live around the world

I learn from this class that a biome is a place where many animals live around the world.The biomes are:Taiga,Deciduos forest,Tropical rainforest,Desert,Tundra and Grasland.

Summary #6

Surviving in ecosystem



I learn from the class of surviving in ecosystems that many animals survive in their ecosystem because
many animals camuflage.Also that there are many kinds of organisms that interact.There are symbiosis,parasitism,commensalism and mutualism.A relationship between two kinds of organisms that last over a period of time is called  sysmbiosis.When a relationship between two kinds of irganisms benefits both of them, it is called mutualism.A relationship in wich one kind of organisms lives on or in another organism and may harm that organism is called parasitism. The relationship where one organism benefits from another without harming or helping it is called commensalism.

Summary #5

Symbyosis.



I learn that symbiosis are two organisms relating over a long time.Commensalisms are two organisms benefit and none is harmed.In mutualism both organisms benefit.And in parasitism one organism is benefit and the other is harmed.

Summary #4

Cycles of life.



I learn that there are three cycles of life that are:water cycle,carbon cycle and nitrogen cycle.In the water cycle it goes first from the evaporation that changes liquid to gas. Condensation is the change from gas to liquid.Next come the freezing that changes liquid to solid.And the melting that is from solid to liquid.Then everything start again.Other cycle of life is the carbon cycle that is when we breath and when we use a lot of cars we give carbon to the plants and the plant give us CO2 that is oxygen.Thats why when we burn a tree,itbecomes carbon.The other cycle of life is nitrogen cycle that is that the air have nitrogen and the decompossers are eaten by fungi and bacteria and ammonia and then it goes from the nitrites and to the air again.

Summary #3

Food chains and food webs


I learn from the food chains and food webs that in the food chain,energy is passed from one link to another.And in the food web are different living things that represents tha the strongest eat the weakness.

Summary #2

Living things and their environment.


I learn that the environment is an area where animals live.Also i learn that the ecosystem have factors that ar biotic and abiotic.Biotic are living thins like animals, plants, fungi,protist, bacteria.etc...And abiotic are nonliving things like temperatures,minerals,light,air,water,soil,rocks.etc...

Summary #1

Energy Resources



I learn from the energy resources that the persons use energy the 24 hours of the day but when we are slepping,we use less energy because the energy is just consentrating in breathing and on the digestive system.
To get energy we need food and oxygen,that means that food + oxygen = energy.Some examples of alternative energy resourcesare wind energy,water energy,solar energy,geothermal energy. etc...
