In order for a population to survive certain variables must be in place‚ making the biome ideal to support life for that and the other species within that community. There are some species that depends solely on the type of climate and food web that is available in a particular biome‚ these species would be considered to be specialists. Other species are able to adapt to the change of climate and eat a variety of items which aids in

A soil horizon is a layer parallel to the soil surface‚ whose physical characteristics differ from the layers above and beneath. Each soil type has at least one‚ usually three or four horizons. Horizons are defined in most cases by obvious physical features‚ chiefly colour and texture. These may be described both in absolute terms (particle size distribution for texture‚ for instance) and in terms relative to the surrounding material‚ i.e. ‘coarser’ or ‘sandier’ than the horizons above and below

The spider I’m doing my report on is called the Golden Orb spider‚ better known as the banana spider. 0The golden orb spiders are found in dry open places in forests‚ woodlands‚ coastal sand dunes‚ shrubland‚ and mangrove habitats. Some of the golden orb spiders live nearby bushes and flowers. All orb weaving spiders make suspended‚ sticky‚ wheel-shaped orb webs. The webs are placed in the openings between trees and shrubs where insects mostly fly. There are species of banana spider in Africa (including
