Ecosystems

Ecosystems are collection of areas where the living things interact with non-living to create what we as our biosphere. Biotic and abiotic are the scientific terms for describing living and non-living factors in the ecosystem. Sort the items below int he co Sort the items below in the correct categories. Biotic flower grass worms bacteria roots of the plant apple tree fish eggs in a nest bird decomposing log Abiotic soil sun nest rocks air rain clay river pond plastic bag Match it up! Find the term that correctly completes the following sentences Place an animal lives habitat all of the animals that live together in a area community All the prairie dogs living in a grassland community population plants, grass, trees special role in the ecosystem is to be producers niche There is a maximum number any area can support because of the resources carrying capacity Relationship when two organisms benefit each other mutualism Relationship when one organism benefits & the other is unaffected commensalism How biotic interacts with abiotic factors in the ecosystem Identify whether marked factors are biotic or abiotic. Lichens is made up of fungi and algae both. Both organism benefit each other because fungi provides the shelter and moist environment and algae make food. The relationship is parasitism mutualism competition commensalism Remora fish attaches itself to a shark. The remora travels around with the shark, eating leftover scraps after a kill. The remora does not help or harm the shark. The relationship is parasitism mutalism competition commensalism A tapeworm live inside an animal (host). The tapeworm gets oxygen, water, and food from the animal it lives in, but the animal can get sick or die, so it causes harm. The relationship is parasitism mutualism commensalism predator Matter recycles in the ecosystem, but energy transfers through the ecosystem Identify the transfer of energy in the ecosystem as it moves through each trophic level. Think about how the transfer of energy changes as it moves through each trophic level. If the producer level starts with 20,000 k identify how much the other levels would recieve? Matter recycles because the ecosystem is made up of living organism that are producers, consumers and decomposers Draw or crop a picture of a food chain from any biome that has five organisms, but must include producer, consumers and decomposer in the correct order the energy would transfer. Elements essential for growth and development of animals, but the elements travel in the cycles that are constantly recirculating them. Remember! No matter is created or destroyed! Put the correct cycle name in the green box that names the cycle. Water cycle helps with water from soil, oceans rivers and lakes evaporating and turning into water vapor in the air. Plants take in carbon dioxide during photosynthesis. Plants and animals need nitrogen, but cannot inhale it from the air. Water vapor rises and cools, condensing into tiny drops of water or ice in clouds. Plants use the carbon to make the food for plants. (glucose) Bacteria in the soil remove the air has to be fixed. Precipitation falls as rain, sleet, hail or snow During photosynthesis, plants release oxygen into the air. Converted to nitrates, which is a form plants can use. Most water collects in rivers and returns to the ocean or infiltrates the ground to the aquifer. Animals inhale oxygen from air, but exhale carbon dioxide during respiration. (breathing) Plants take the nitrates in through their roots. Plants get water and release it to the air through traspiration. Dead plants and animals give off carbon dioxide as they decay. Other bacteria in soil take the nitrates and convert it again to release back into the air as nitrogen.
