| Question | Answer |
|---|---|
| environment | anything that can affect an organism. |
| population | a group of individuals who belong the same species and live in the same area. |
| community | a group of populations that interact with each other in certain areas. |
| ecosystem | a community of organisms living together with the nonliving parts of the environment. |
| Abiotic factors | the nonliving parts in the ecosystem. |
| Biotic factors | the living organisms of and ecosystem. |
| the study of how different things interact with each other and their environment is called | ecology. |
| The biosphere is part of _______ in which ________ things are found. | earth living |
| are important abiotic factors that organisms depend on. | sunlight, temperature, water, soil, and air |
| The _____ and _____ parts of and ecosystem interact with one another. | abiotic biotic |
| Part1: Explain how the amount of rainfall in a biome affect the number of organisms it can support. | the number of plants and animals that live in an ecosystem depends on rainfall. Little rainfall means less plants and smaller animals depend on plants for food. Since large animals depend on small animals that means the # of large animals reduce too. |
| Part2: Explain how human actions such as, polluting the air or water and cutting down acres of trees in the rainforest, can show changes in living things. | Air pollution can hurt the air plants need to make food and animals need to breathe. Some organisms depend on water to provide them with oxygen to live. Cutting down trees can take away homes from animals and less photosynthesis takes place. |
| All organisms in a particular ecosystem have ______ that help them survive. | adaptations |
| Adaptation | a charecteristic that helps organisms live and reproduce in a particular environment. |
| Some environments have very harsh _______ _______ like very low temperatures, and long dark _____ . Organisms develop adaptations to live in such environments. | abiotic factors days |
| Biome | large group of ecosystems with similar climates and organisms. |
| each______ is not a particular place, but different ______ __ ___ _____ that share similar charecteristics. | biome areas of the world |
| Each biome consists of different parts of the ____ with similar ______ . | world climates |
| The _______ __________ has many more species than any other ______. | Tropical rainforest biome |
| As the _______ ____ lose their leaves each year, they fall to the ground and ______, as a result the _______ of the ____ _____ is nutrient rich. | forest trees decay soil deciduous forest |
| the _____ _____ _____ of the caribou helps keep it warm during the long _______ winter. | long thick hair taigia |
| _________ don't receive enough rain to support many large trees. | Grasslands |
| An important feature of the _____ is its permanantly frozen soil just beneath the surface. | tundra |
| _______ _______ including cacti and other plants have short growth systems. | Desert plants |
| Some scientists study 5 biomes [we studied6]. What advantages and disadvantages is using 5 biomes instead of 6 we used.[name 2 reasons]. | The 5 categories add quatic which include ocean,river, and lakes. These are divided among the 6 we studied it doesn't have it's own.because water covers so much of the earths surface, there are many different climates associated with it. |
| Finish 5 biome short answer! | for the same reason grouping forests into one biome doesn't help us to understand the differences in tropical and deciduous forests. the 5 categories don't rely on climate as the major differences between the biomes. |
