Summary: Surviving in the Ecosystem


       To survive in an ecosystem first you need to adapt. Then have some Simbiosis. Simbiosis is the interacting of the animals with each other. there are three tipes of simbiosis. 1 Mutualism: in mutualism they benefit both. An example can be a flower and a bee. 2 Parasitism: in parasitism one harm the other one. An example can be a dog and a fley. 3 Commensalism: a relasionship when one benefit withoug harming the other one. An example can be the yucca tree and the yucca moth.

Summary: Cycles of Life


       Water cycle can begin were you want. It normaly begins with evaporation wen the water turn from liquid to gas. Condensation is the turn of gas to any precipitation depending on the temperature, it can be hail, rain, snow, sleet, due, ect. Presipitation is the tuning of liquid to gas to liquid that falls from the clouds.
       Carbon dioxide enters the air when plants and animals decay. It enters the air when animals breath out. It enters the air when fossil fuels such as coal, oil, gasoline, and natural gas are burned. Forest fires also ad carbon dioxide to the air.
       Air is made up of 78 percent of nitrogen gas. some bacteria that grow on pea and bean root give those plants the nitrogen they need. Plants absorb nitrates disolved in water throug their root. The nitrogen is then used by the plants to make proteins

Summary: Food Chains and Food Webs


       Food Chains begins always with energy, that is the sun. The producer, that is the plant, transfer the energy to the consumer, that is the grasshoper. Then the energy is pass to the 2 consumer, that is the snake. then our 3 consumer is the hawk that eat the snake and then the hawh pop and then it decompose and grow a new plant.
       Food webs begins with the producers that are trees, grass, ect. organisims that cannot make their oun foods are consumer that eat producers.
They can eat also other consumers that is cal the pray. The predator eats the prey then the predator pop and make dicomposers.

Summary: Living Things and Their Environment


        Living Things and Nonliving Things live in an ecosystem and they interact each other. Some ecologist study this interacting and they see symbiosis. There are three (3) tipes of symbiosis that are: mutualism, they benefit both; parasitism, one harm the other; commensalism, they dont harm each other.
       Biotic and abiotic factors are like living things and nonliving things. Some biotic factors are: animals, plants, bacteria, protist, fungi and many others. Someabiotic factors we cand find: wind, air, light, water, minerals and many others.
        A population is like a big building with humans in it. When this population joint with other population with different species form a big community and a habitat. Each one of this community have a niche, an ocupation. My niche is to be a good student for the country.

Summary: Energy Resources

         The humans have an adaptation in the energy sources specially we use fossil fuels. The problem with fossil fules is that they take too much time to be made by it self and they pollute the air. But there are other sources of energy that are called alternative sources of energy that dose not pollute. We can find four (4) alternative energy that are: Wind energy, Water energy, geothermal energy (Earth´s internal energy) and solar energy.
       Fossil Fuels form by decaied plants and animals in the soil (humus).They form in steps: Step 1: dead plants and animals fall to the ocean floor. Step 2: dead plants and animals are covered with layers of sand and mud. Step 3: over millions of years, preasure and heat helped to turn dead plants and animals remains into oil and natural gas.
       Methane gas is a tipe of gas that we use to cook in our kitchens and houses. A example of an object that make methane gas is the corn you just need to let him decompose and it form an imflamable gas.
