Organisms depends on physical and biological factors of an ecosystem.
Explanation:
Biological and physical changes cause shift in an ecosystem's populations because the population of organisms depends and greatly affected from the environmental factors such as temperature, moisture etc. These environmental factors causes change in the physical features of an ecosystem so when these changes occur in physical factors, it greatly affected the population of organisms.
Answer:
4 possible combinations of gametes
Explanation:
The animal is considered an heterozygotic dihybrid because it involves two genes that have different alleles for both genes. The dihybrid animal undergoes meiosis to produce gametes. According to Mendel in his laws of segregation and independent assortment, the alleles of the two genes separate into gametes independently of one another to produce 4 types of gametes.
Number of possible combinations of gametes formed by an heterozygote can be determined by using 2^n, where n is the number of characters. Number of characters or genes involved in this case is 2, Hence, 2^2 = 4 gametes.
The allelic combination in the four gametes are: AB, Ab, aB, ab.
Energy is always lost as energy is moved from one level to another. ... The loss of energy due to the second law of thermodynamics results in a pyramid with a large base and a 10% ratio between levels.
