What is the life cycle for a goldfish?​
Rus_ich [418]

Answer:

The life cycle of a goldfish starts out as an egg. The female fish will lay about 25 eggs, but unfortunately only some grow up. The eggs usually hatch within 5 days and if you have a fish tank then you should take the adult fish out or else it may eat the eggs. After the egg hatches, it turns into a fry,(this is what a baby goldfish is called) Once they hatch, they will stay attached to the plants for two days, after that, you should start to feed them. Once they are not fry anymore, they turn into adult goldfish. If you take care of them properly, they could last up to 15 years! Once the fish are complete adults, they can lay eggs. The females rub up against plants and lays eggs while the male Goldfish sprays the eggs to make them fertilize and turn into fry.

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.
