Answer:

The correct answer is- IgA

Explanation:

There are five types or class of antibodies found in the human body these are IgA, IgM, IgD, IgE, and IgG. Out of these five class IgA antibody is found in an abundant amount in the mother's milk or colostrum.

Infant take this antibody from the mother through breastfeeding which protects the infant from may pathogenic microbes. The immunity in which antibodies are taken from outside is called passive immunity.

Therefore the passive immunity source that is given by the mother to baby through breast milk is called IgA.

In a food chain 200 kg of wheat is fed on by 18 kg of mice which in turn are eaten by 1kg of hawk. What is the percentage energy
Nikolay [14]

Answer:

0.1% of energy

Explanation:

Energy flow: From the whole quantity of energy that reaches the earth's surface, autotroph organisms or producers absorb only 0.1 or 1%.

From the input of solar energy begins a unidirectional energy flow through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is dissipated in the environment.  

At each trophic level occurs an energy transfer to the next, with only 10% being usable in each of them. This assessment is called "The 10% rule". As a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time.

If wheat transferred 10% of the energy to mice, and of that 10% mice transferred 10% of the energy to hawk, then the percentage of energy transferred from the first trophic level to the third equals 0.1%.

10% (1st TL-2nd TL) / 10% (2nd TL - 3rd TL) = 0.1% (1stTL - 3rd TL)

<em>TL = Trophic level           </em>
