Explain the 1st and 2nd law of thermodynamics in terms of food chain, energy flow, pyramid of number and pyramid of energy
Westkost [7]

Answer:

First law of thermodynamics is the conservation of energy states that energy is not created and not destroyed but only can be stored.

Thermodynamics second law states that total entropy of a system increases from lower to higher system and some of the energy is always wasted during the work done.

In the food chain plants are the producers which accept light energy and stored in the form of chemical energy and energy flow to the herbivores and higher trophic levels in the chemical form only and no new energy is created in between the chain (Fisrt law of thermodynamics). Heat is generated during respiration by plants and animals (wasted energy) and entropy also increases with the increase in level of the pyramid of energy (Second law of thermodynamics).

Mendel’s law of independent assortment states that alleles of genes on nonhomologous chromosomes assort independently during gam
Lera25 [3.4K]

The mix of alleles from various genes that end up in the daughter cells is determined by the anaphase 1 of meiosis 1.

Chromosome segregation during meiosis is mirrored in the segregation of alleles. During anaphase, 1 of meiosis 1 homologous chromosomal separation leads to allele segregation.

Chromosomes display autonomous assortment when they are randomly split into daughter cells during meiosis.

<h3>What takes place in anaphase 1?</h3>

During meiosis I, sister chromatids remain together as homologous chromosomes separate. To appreciate the development of germ cells, it is crucial to comprehend how this odd chromosomal segregation behavior came to be. Here, we show that the pattern of chromosomal segregation during meiosis I is determined by the microtubule-kinetochore interactions that are inhibited during prophase I and the premeiotic S phase.
