Ecosystems are composed of a variety of abiotic and biotic components that function in an interrelated fashion. Some of the more important components are: soil, atmosphere, radiation from the Sun, water, and living organisms.
Soils are much more complex than simple sediments. They contain a mixture of weathered rock fragments, highly altered soil mineral particles, organic matter, and living organisms. Soils provide nutrients, water, a home, and a structural growing medium for organisms. The vegetation found growing on top of a soil is closely linked to this component of an ecosystem through nutrient cycling.
The atmosphere provides organisms found within ecosystems with carbon dioxide for photosynthesis and oxygen for respiration. The processes of evaporation, transpiration, and precipitation cycle water between the atmosphere and the Earth's surface.
Solar radiation is used in ecosystems to heat the atmosphere and to evaporate and transpire water into the atmosphere. Sunlight is also necessary for photosynthesis. Photosynthesis provides the energy for plant growth and metabolism, and the organic food for other forms of life.
Most living tissue is composed of a very high percentage of water, up to and even exceeding 90%. The protoplasm of a very few cells can survive if their water content drops below 10%, and most are killed if it is less than 30-50%. Water is the medium by which mineral nutrients enter and are translocated in plants. It is also necessary for the maintenance of leaf turgidity and is required for photosynthetic chemical reactions. Plants and animals receive their water from the Earth's surface and soil. The original source of this water is precipitation from the atmosphere.
Ecosystems are composed of a variety of living organisms that can be classified as producers, consumers, or decomposers. Producers or autotrophs, are organisms that can manufacture the organic compounds they use as sources of energy and nutrients. Most producers are green plants that can manufacture their food through the process of photosynthesis. Consumers or heterotrophs get their energy and nutrients by feeding directly or indirectly on producers. We can distinguish two main types of consumers. Herbivores are consumers that eat plants for their energy and nutrients. Organisms that feed on herbivores are called carnivores. Carnivores can also consume other carnivores. Plants and animals supply organic matter to the soil system through shed tissues and death. Consumer organisms that feed on this organic matter, or detritus, are known as detritivores or decomposers. The organic matter that is consumed by the detritivores is eventually converted back into inorganic nutrients in the soil. These nutrients can then be used by plants for the production of organic compounds.
A self sustainable ecosystem is an ecosystem, that takes care of it self e.g. a fish tank would be an un-natural ecosystem since it is made. Not only is is made but also the fishes living their depend on we, the owners of the tank to feed them and clean their tank in order for them to survive. Thus such an ecosystem is comprised of interdependent organisms (plants,animals and insects) who would through a food chain create an energy flow.
some thing that is able to sustain oneself or itself independently
primary producers ( autotrophs)......cycling?......constant source of energy??(sun) this is a Q on my AP bio summer work grrr and i dont get it rele either =(
producers, decomposers.. That's it
A neutral atom must contain an equal number of electrons because it is a neutral atom.
A geographic area that plant and animal life and the natural process that sustains them live is called an ecosystem. An ecosystem must have the conditions right for survival of inhabitants.
water, food, energy, oxygen and needs to be a suitable living condition. these are the 6 parts that make up an ecosystem. the different parts of an ecosystem are;primary producers,primary consumers,secondary consumers,tertary consumers and the decomposers help to make an ecosystem.........ecosystems contain biotic components-living organisms that inhabit the ecosystem as well as abiotic components of an ecosystem include water, soil, sunlight, minerals and other non-living things.
By definition, ethers must contain at least one oxygen atom.
No because each animal has its one ecosystem
Yes. If you have an ecosystem you automatically know there is a habitat and community in it. It takes both to make an ecosystem. Hope I helped.
Ecosystem, stemware, systematic.
A producer
Nitrogen must be cycled through an ecosystem so that the nitrogen is available for organisms to make proteins.
The if statement must contain else.
A term must contain a variable, for it to be relevant.
A Plasma must contain many ions and electrons.
Most marine ecosystems do contain saltwater. Some bodies of water do contain freshwater, but they are not the majority.
a spoon
producers, decomposers.. That's it
Resources must be limited in the ecosystem.
