a) Biotic describes a living component of a community; for example organisms, such as plants and animals. b) abiotic components (also known as abiotic factors) are non-living chemical and physical factors in the environment which affect ecosystems. c) Herbivores are organisms that are anatomically and physiologically adapted to eat plant-based foods. Herbivory is a form of consumption in which an organism principally eats autotrophs such as plants, algae and photosynthesizing bacteria. More generally, organisms that feed on autotrophs in general are known as primary consumers.
Insects eat plants, birds eat insects, bacteria and fungi in the soil decompose birds and other organisms when they die, and plants obtain vital nutrients from the soil. Food webs for ecological communities may be extremely complex. 4.How could human behaviors and rising human populations impact these cycles? Humans can eliminate species and life by pollution or killing. Humans need to monitor their actions by moving life to a new location
To summarize what this article talked about it was a study done on the effects of soil degradation and the effects on the vegetation in areas around watering points and normal grazing lands. The study showed that in these ecosystems the overgrazing reduced the ecosystem diversity of plants in poor soils. It also talked about how overgrazing around certain areas can not only destroy the soil but it can also cause the destruction of certain types of species. Overgrazing differs in all areas of the world but it still has a common problem which is that when there is overgrazing no matter what type of environment you are in that environment will be
Many of the aquatic invertebrates are responsible for keeping the ecosystem clean by feeding on litters. Extinction of theses invertebrates would totally disrupt the balance of the ecosystem. The aim of this study is to bring awareness about the harmful impact global warming has on the local aquatic invertebrates and on the ecosystem at a global scale. The hypothesis for this study is that the biotic diversity of the slow moving water and fast moving water are driven by abiotic factors. To support this hypothesis, three predictions were made.
What is the Ecological Footprint? The Ecological Footprint is a resource accounting tool that measures how much biologically productive land and sea is used by a given population or activity, and compares this to how much land and sea is available. Productive land and sea areas support human demands for food, fiber, timber, energy, and space for infrastructure. These areas also absorb the waste products from the human economy. The Ecological Footprint measures the sum of these areas, wherever they physically occur on the planet.
I concur with the court’s rulings to some degree. I believe a manure aroma from the farm is unavoidable; therefore, a prudent person who moves next to a dairy farm should expect an odor. It would be irrational to force the dairy farm to eliminate the smell, especially since the manure is required to fertilize the soil. Consequently, the smell does not constitute as a private nuisance to Sam Anxious as it fails the test of reasonableness. Although the odor is reasonable to expect, the broken pipe that poured manure into Mr. Anxious’s yard caused a trespass.
Tropical Savanna A biome is a large geographical area of distinctive plant and animal groups, which are adapted to that particular environment. The climate and geography of a region determines what type of biome can exist in that region. Major biomes include deserts, forests, grasslands, tundra, and savanna. Each biome consists of many ecosystems whose communities have adapted to the small differences in climate and the environment inside the biome. Any change in one part of an environment, like an increase or decrease of a species of animal or plant, causes a ripple effect of change in through other parts of the environment.
Were we to become extinct, their domesticates would most likely not survive. These would include pets, livestock, and crop plants. Species whose populations would likely grow would be the ones human activities have had a detrimental effect on, such as whales, mountain gorillas, and the many weeds we struggle to keep in check. 7. How would you respond to someone who tells you: (a) that he or she does not believe in biological evolution by natural selection because it is “just a theory,” and (b) that we should not worry about air pollution because natural selection will enable humans to develop lungs that can detoxify
