Answer:
First off, we need to establish what secondary consumers are. Primary consumers are all herbivores; they eat the producers. The secondary consumers are on the next trophic level up; they eat the primary consumers. They thus help to control the level/number of primary consumers; otherwise, the number of primary consumers would grow too high, and the producers would all be WIPED OUT.
Now, you may be wondering what controls the amount of secondary consumers? The answer is tertiary consumers. What controls the tertiary consumers? At this point, energy does the job of limiting the population. As you move up trophic levels in an ecosystem, the amount of energy in each trophic level goes down by 90%. So like if you started w/ 1000000 joules of energy in the producer level, that would be 100000 in the primary, 10000 in the secondary, and only 1000 in the tertiary.
Answer:
Graafian follicle
Explanation:
Ovulation is the process observed in the females during which the females release the oocyte or the female egg cell. The process of ovulation takes place every month during the 14th day of the menstrual cycle.
The primary follicle is formed in the females before birth but after the puberty, each month the primary follicle matures into the secondary and then tertiary follicle called the Graafian follicle. This Graafian follicle releases the secondary oocyte.
Thus, Graafian follicle is the correct answer.
Answer:
You need to have a basic understanding of how things work in biology. The optical properties of sea-water are of immediate importance in biology, as they affect the penetration of sunlight into the depths.
Explanation:
Biology is the study science of life. This name is derived from the Greek words ,"bios" (life) and "logos" (study). The scientists that study biology are called biologists. Biologists study the structure, function, growth, origin, evolution and distribution of living organisms.
Hello!
The type of polymer that is made by bonding an alkene to one or more alkanes or alkenes is called addition polymer
Addition polymers are those whose polymerization reaction doesn't produce low molecular mass compounds but the bonding of molecules one after the other. Such a reaction implies that there is a rupture in the bonding between monomers (the building blocks of the polymer) to allow the formation of a chain.
Bonding an alkene to one or more alkanes or alkenes is an example of an addition polymerization.
Have a nice day!
