Answer:

The human circulatory system has a complex network of blood vessels that reach all parts of the body. This extensive network supplies the cells, tissues, and organs with oxygen and nutrients, and removes carbon dioxide and waste compounds.

hope this helps!

Answer: It provides protection of the body by white blood cells, antibodies, and complement proteins that circulate in the blood and defend the body against foreign microbes and toxins. Clotting mechanisms are also present that protect the body from blood loss after injuries.

Use the model here to describe the transfer of matter and flow of energy from one trophic level to another within an ecosystem.
Andrews [41]

The food chain and food web are used to transfer energy. Plants, who are the primary energy providers in the ecosystem, use their chloroplasts to collect sunlight, which is then partially converted into chemical energy during photosynthesis.

a)

  • When herbivores eat (are the primary consumers of) plants as food, this energy is transferred to the primary consumers in the food chain.
  • This energy is stored in various organic products in plants. Then, the chemical energy contained in plant products is converted into kinetic energy, degrading the energy by turning it into heat. The secondary consumers come next.
  • Further deterioration will occur when these herbivores are consumed by secondary consumers.
  • Finally, energy will once more be destroyed when tertiary consumers eat the carnivores. As a result, the energy flow is only in one direction i.e., unidirectional.

b)

  • Additionally, the energy flow in a food chain adheres to the 10% law.
  • This law states that only 10% of energy is transferred from one trophic level to the next, with the remaining 90% being lost during the digestion process of the organism itself.

c)

  • There are typically fewer organisms at the top of an energy pyramid because It has the least quantity of energy, the top level of an energy pyramid has the fewest organisms.
  • Most ecosystems only have four trophic levels because there is eventually insufficient energy to maintain further trophic levels.

d)

  • For instance, let us assume that a plant at the producer level produces 1000 Kcal of energy.
  • When a primary producer eats this plant, it will only get 10% of the energy produced by the plant i.e., 1000/10 = 100 Kcal. the rest 90% will be used up by the plant itself for its metabolism.
  • Further when a secondary consumer eats the primary consumer, it will only get 10% of the energy produced by the plant i.e., 100/10 = 10 Kcal.
  • Lastly, as the tertiary consumer eats the secondary consumer, it will only get 10/10 = 1kcal.
