The two richest ecosystems lie in tropical rainforests and coral reefs. On land, tropical rainforests contain many species variation with an abundance of species in bird, mammals, amphibians, and plants. While tropical rainforests occupy only 7 percent of the Earth’s land area, they contain over half of the world’s species. This may be because species richness tends to increase with decreased elevation, increasing solar exposure, and increased precipitation; that is, hot, rainy low-land areas have the most species. In contrast, deserts have low species variation because of low precipitation. On earth, water is majorly important the equation for life. Many of the species are genetically isolated because of habitat size and variation in the build of the land (mountains, equator location, etc) such as seen in the Galapagos islands and the Amazon rainforest, both near and in South America.
Hope this helps!
The correct answer is it lives inside or on a host.
A is incorrect because a parasite steals from the host, without giving anything in return. Much like a leech
C is incorrect because leeches almost always use their host as a food source
D is incorrect because parasites can often dig beneath the host's skin to be hidden from sight
Answer:
Recombinant DNA
Explanation:
Recombinant DNA can be used to change the genetic makeup of a cell, as in adding a gene to make a bacterial cell produce insulin.
B. sunflower is the answer .....I think so if wrong correct me.............!!!!!!!!!!!!!!
In describing the energy transfer of trophic levels, energy is lost as we move up from a lower level to a higher level. This is because energy is used when for example a primary consumer does body processes before it is eaten by another consumer. hence the lowest trophic level belongs to those which <span>2) has the greatest biomass</span>
