A small, colourless organelle that gives rise to a plastid (e.g. chloroplast, chromoplast, and leucoplast) Supplement. A proplastid is an organelle found in the meristematic regions of the plant.
I believe the answer to this is It provides care to the Young (unless that wasn't part of the choices if so then it should be 2).
Answer:
esta es la respuesta
Explanation:
Sin el sol, no habría fotosíntesis y la vida no sería sustentable. La fotosíntesis es la reacción química donde el dióxido de carbono (CO2) y el agua forman azúcares y producen oxígeno en presencia de energía lumínica.
Answer: a. disease
b. food availability
d. reproductive success
f. predation
g. light availability (to plants)
h. physical space
Explanation:
The density dependent factors are the factors which effects the population of a species depending upon it's size or growth. The following are the density dependent factors.
a. disease: A disease is a density dependent factor this is because of the fact that a disease can spread directly when the population size is large.
b. food availability: With the increase in the size of the population will increase the demand for food. This can cause scarcity of food, the population will decline.
d. reproductive success: The increase in the size of population will increase the likelihood of mating success hence, this will support reproductive success.
f. predation: The large population of prey will attract the population of predators hence, the population of the prey will decrease due to large density.
g. light availability (to plants): The increase in plants typically of tall height can affect the light availability to the small plants.Thus the population of small plants will die due to the fact that they will not receive sunlight.
h. physical space: The physical space is the area occupied by the organism as a habitat. With the increase in density of the population of a species the competition for physical space will increase which will lead to the decline in the size of the population.
