Benefits[ edit ] Seed dispersal is likely to have several benefits for different plant species.
Ecofeminism and ecopsychology are mentioned, for example, as are terms from organic gardening and permaculture. Because the life sciences messily overlap that's lifeterms from botany, biology, geology, chemistry, meteorology, and agriculture are included as well.
Although designed for technical correctness and clarity, this glossary follows the practice in the Jung and Freud glossaries at this site of letting in a bit of humor here and there: Some states in the U. Abrasiveness also seems to be the one quality currently shared by most political appointees and prominent heads of state.
Also refers to how objects convert the solar radiation they receive into heat. Acids tend to be sour and corrosive. The human stomach contains hydrochloric acid with a pH of 1; battery acid is stronger, but not by much.
Most of it is generated by sulfur dioxide and nitrogen dioxide air pollution. Its pH is less than 5. Results include fish and plant deaths, corrosion, groundwater pollution, and soil erosion. Its long-term effects are unknown. See Plate Tectonics for more about what causes accretion.
The standard measure of agricultural irrigation. They produce antibiotics, enzymes, and vitamins, although a few are harmful to humans. In this the organism is not a passive recipient of external circumstances; the relationship is interactive.
It often happens after some kind of catastrophe empties a range of ecological niches simultaneously.
A warm breeze through a relatively cool orchard, for instance. Examples include dunes, deflation hollows, and sand-blasted outcroppings. Certain small seeds, bacteria, and spores are examples. Often has the effect of making the bed of a stream or flood plain rise.
Also, a phase of forest biomass accumulation in the years that follow a harvest. The Agricultural Neolithic Revolution began ten thousand years ago in the Fertile Crescent, where extensive irrigation turned once-fertile croplands into barren salt pans. By some accounts, the now-denuded Zagros Mountains in western Iran hosted this revolution.
Modern agriculture largely relies on keeping ecosystems in perpetually immature states of succession in which chemically stimulated productivity remains high until the soils are too depleted to grow anything. The corporatization of farming, resulting in a handful of very large non-local companies owning and managing--and in some cases ruining--millions of high-yield acres.
According to the Environmental Protection Agency, half the water pollution in the U. Most of the other half is industrial. Auto emissions run a close second.Plant Adaptations Introduction.
Living things must be correctly adapted to their basic needs and to the environment in which they live. In the case of plants, the environmental factors of major importance are temperature and moisture.

39 5. Given below are some adaptive features of animals: (i) Layer of fat under the skin (ii) Long, curved and sharp claws (iii) Slippery body (iv) Thick white fur. It grows in forest edges and opening. Many kinds of wildlife eat its small fruits. Although the fruit is harsh and puckery, people sometimes use it in making jellies.
Rain forest animals and insects often use bright coloring and distinctive markings to scare predators. Some of these creatures, such as certain species os poison dart frogs, actually are dangerous, but some aren't.
