Which statement best contrasts food chains and food webs? Food webs show a single path of energy in an ecosystem, and food chain
s show all the overlapping food chains in that ecosystem. Food chains show a single path of energy in an ecosystem, and food webs show all the overlapping food chains in that ecosystem. Food webs show the path of energy in an ecosystem, and food chains show the path of nutrients in that ecosystem. Food chains show the path of energy in an ecosystem, and food webs show the path of nutrients in that ecosystem.
Answer: Food chains show a single path of energy in an ecosystem, and food web show all the overlapping food chains in that ecosystem.
Food chain is a linear food distribution channel where one organism is fed by the other in order to gain energy. Food chain involves the unidirectional flow of energy starting from lower most trophic level to higher trophic level. This energy distribution is according to the 10% law which suggest that energy at the lowest trophic level is the maximum which decreases by 10% on reaching subsequent higher trophic levels. Therefore, highest trophic level in the food chain receives the least energy. For example, plants are the primary producers of the ecosystem having highest energy these are fed by small animals like goat which are primary consumers, goat further eaten by fox ,which is secondary consumer. Lastly, the fox is eaten by lion ,which is a tertiary consumer. Here, lion will receive the lowest energy among all the trophic levels. Food web is an interconnection between overlapping food chains in an ecosystem. In a food web, food chains are dependent on each other for their food and energy requirements.
Answer:( answer for number one)an essential nutrient for the production of amino acids, proteins, nucleic acids. ( number 2 ) for the growth, maintenance, and repair of all tissues and cells, and for the production of the genetic building blocks, DNA and RNA
<span>one of the special feature of bacterial cells that helps it survive in hostile environment is its : ability to form endospores
Endospores are resistant to chemical, stress, and some form of radiations, which make bacteria abble to survive in the environement</span>
Two types of posterity can be created subsequent to mating: parental and recombinant. Recombinants are created because of the traverse of non-sister chromatids at the hour of gamete arrangement. Here, mating happens between m+g/mg+ female and mg/mg male so the posterity would be separated as follows:
m+g/mg : Parental
mg+/mg : Parental
m+g+/mg : Recombinant
mg/mg : Recombinant
m+g+/mg (wild sort) and mg/mg (smaller than usual wings, garnet eyes) are the recombinants thus they were created because of the hybrid occasion.
Hence,the right answer is option 2 & 4 "wild type and miniature wings,garnet eyes"
The cell cycle or cell-division cycle is the series of events that take place in a cell leading to its division and duplication of its DNA (DNA replication) to produce two daughter cells.
