Both biome and <span>ecoregion </span>are ecological terms. Biome refers to a major regional group of plant and animal communities adapted to the natural environment. Biome can be of two types: terrestrial(land) andaquatic(water). <span>Ecoregion, </span>which is an abbreviated form of ''ecological region', refers to a smaller class. Each <span>biome </span>consists of severalecoregions, an ecoregion(also called bioregion) covering a realm of land/water having geographically distinctive communities, sharing the same envoronmental conditions and ecological dynamics.
Yes, an ecoregion does consist of different ecologically distinctive communities and species.
The answer is d. pheromones.
Answer:
$130,410
Explanation:
According to this question, a small family farm has 230 acres of farmland to grow corn. Each acre yields 63 bushels of corn i.e 1 acre = 63 bushels of corn
Also, each bushel can be sold at $9.00 i.e. 1 bushel = $9.00
If 1 bushel = $9.00
63 bushels = 63 × 9 = $567
Since 63 bushels of corn = 1 acre, it means that $567 is made on one acre.
Hence, on 230 acres, 230 × 567 = $130,410 will be made on corn per year
Color patterns can be thought of as mosaics of different-sized, form, brilliant, and colored patches. A number of natural conditions, including ambient light, watercolor, viewing distance, and the visual capabilities of guppies and three of their predators, were used to assess how noticeable guppy color patterns were.
A particular color pattern element (patch reflectance )'s spectrum, the medium's transmission spectrum, and the ambient light spectrum that strikes the patch all interact to determine the light spectrum that reaches the eye's surface (air or water).
The light at distance x from the patch that reaches the eye at any given wavelength, I, is the result: Q(& x) is the photon flux from the patch reaching the eye (patch radiance), and Q(A) is the photon flux of ambient light incident on the patch.
Predation intensity varies spatially with guppy color patterns, which are influenced by the make-up of the predator communities (Endler, 1978). As a result, calculations were made independently for the color patterns of guppies that are unique to three different predator communities.
