Energy is lost between trophic levels.
Answer: Option C
Explanation:
The source of energy for all organisms is the Sun. The Tropic levels exhibit the flow of energy in an ecosystem. The flow of energy is always in one direction. The energy level decreases crossing each trophic level as energy is lost in the form of heat.
Primary producers are the first in Trophic level, The Herbivores fall in the next level , the Carnivores form the next level and the decomposers are the last in the trophic level. The decomposers decompose all the living organisms and convert to nutrients that are available in the soil. The plants take up this nutrient and hence this is a cycle.
Answer:
yes
Explanation:
from coming all the way from our common ancestors , we have genes and DNA that are similar that and shows relation to each other
Sponges get their food through a process of filter feeding. Water-carrying food particles enters the sponge's body through tiny pores, is filtered by specialized cells, and the undigested water then flows out through larger openings. The sponge's body essentially acts like a sieve, filtering food from the water.
Sponges, belonging to the phylum Porifera, are simple multicellular organisms that reside in aquatic environments. Sponges obtain their nutrients by filter feeding. This process is accomplished through a system of specialized cells and water canals within the sponge's body. Water laden with tiny organic particles and microscopic plankton known as the sponge's food enters the sponge's body through tiny pores called ostia. This water is then filtered through chambers lined with specialized cells called choanocytes or collar cells. The collar cells whip up a current with their flagella, making the water flow through the sponge. The food particles are captured by the choanocytes and digested by them or by other specialized cells called amoebocytes. Then, the filtered water leaves the sponge's body through larger openings called oscula. Thus, the entirety of the sponge’s body acts as a sieve for feeding, filtering out microscopic food particles from the surrounding water.

Nerve and muscle are the cells that no longer undergo mitosis.
A cell must go through either mitosis or meiosis in order to divide. Since neurons are somatic cells, they must go through mitosis. Centrioles must travel to the poles and generate spindle fibers that pull the chromosomes in order for mitosis to take place.
Neurons cannot undergo mitosis because they lack centrioles, which prevents them from dividing.
In our nervous system, each nerve cell has a unique location. Its sole responsibility is to transmit a signal from one place to another. In a particularly complicated system, adding more nerve cells might disrupt these extremely precise connections.
Therefore, Nerve and muscle are the cells that no longer undergo mitosis.

Answer:
The phenomenon of unequal separation in meiosis is called nondisjunction. If nondisjunction causes a missing chromosome in a haploid gamete, the diploid zygote it forms with another gamete willcontain only one copy of that chromosome from the other parent, a condition known as monosomy.
