Energy is transferred from one trophic level in a food chain to another. However, not all the energy available at a trophic level is transferred to the next.

Only about 10% of the energy in the lower trophic level gets to the immediate higher trophic level and the rest is lost as metabolic heat.

Thus, if a food chain starts with 10,000 grams of phytoplankton, the quantity that will get to the highest trophic level would depend on the number of intermediate trophic levels in between the lowest and the highest.

For every step the energy is transferred up the trophic level in the food chain, 90% of it is lost.

Answer:

F1: Aa Bb Cc: 4.5 lbs

F2: Too many to list: Between 3 lbs and 6 lbs

Explanation:

F1: Aa Bb Cc, will be the genotypes and will weigh 4.5 lbs, the reason for that is because each capital letter allele adds half a pound to the base weight of 3 lbs.

F2: There are many different genotypes that can be present in the second generation, for example (AA BB CC, AA BB Cc, AA BB cc, etc.) each of which will allow the plant to grow to a certain height. The majority of phenotypes will be 4.5 lbs. There will be one who is AA BB CC, and another one person who has the code, aa bb cc.

Explain five ways in which goat production contribute to the economic development of your country​
Olegator [25]

Answer:

Sheep and goats are important livestock species in developing countries. Of the world's 1,614million sheep and 475 million goats, 65% and 95%, respectively, are located in developing countries. Fifty-three percent of the total small-ruminant population in the developing countries is found in Asia, particularly in India and Pakistan, 33% in Africa, and 14% in Latin America (FAO, 1984).

Goats are hardy and well-adapted to harsh climates. Due to their grazing habits and physiological characteristics, they are able to browse on plants that would normally not be eaten by other livestock species. Thus, the presence of goats in mixed species grazing systems can lead to a more efficient use of the natural resource base and add flexibility to the management of livestock. This last characteristic is especially desirable in fragile environments.

Sheep and goats contribute to a broad range of production systems. The most common system throughout the developing countries involve either the extensive system with large herds and/or flocks grazing on arid and semi-arid rangelands or the intensive system with smaller herds and/or flocks kept in confinement, mostly in the humid tropics.
