A land developer and several ecologists are discussing how a parcel of private land should be developed while saving 20 hectares as natural habitat. The land developer suggests that the 20 hectares be divided into twenty separate 1-hectare areas. The ecologists suggest that it would be better to have one intact parcel of 20 hectares. What is the significance of these different arrangements of the 20 hectaresA. The isolated hectare piots increase the ability of individuals to disperse from one habitat to another. B. The large plot will create more inbreeding in many species C. There really is no difference: they should both work equally well. D. The isolated plots are more vulnerable to edge effects.

Answers

The correct answer is option d. The isolated plots are more vulnerable to edge effects.

Land builders and ecologists are imparting special guidelines for saving the land of 20 hectares of herbal habitat. Both have a special technique for growing the land, the land developer indicates to divide the land into twenty-one-hectare regions. While the ecologist indicates that it might be higher to have one intact land. The land with remoted regions is extra susceptible to part consequences.

Edge consequences are the amendment or extrude withinside the shape of the network that affords at the brink of the 2 or extra than habitats. Areas with small habitat fragments display excessive part consequences.

What is ecology?

Ecology is the have a look at the relationships among dwelling organisms, together with humans, and their bodily environment. Ecology considers organisms on the individual, population, community, ecosystems, and biosphere level.

Hence concluding that isolated plots are more vulnerable to edge effects is the correct answer.

Answer:

The correct answer is option D.

Explanation:

Land developers and ecologists are providing different suggestions for saving the land of 20 hectares of natural habitat. Both have a different approach for developing the land, the land developer suggests to divide the land to 20 one hectare areas. While the ecologist suggests that it would be better to have one intact land. The land with isolated areas is more vulnerable to edge effects.

Edge effects are the modification or change in the structure of the community that presents at the edge of the two or more than two habitats. Areas with small habitat fragments show high edge effects.

Thus, the correct answer is option D.

A habitat is an ecological or environmental area which is inhabited by particular species of animals, plants, or other type of organism.
Environmental factors that create different habitats include:
temperature
topography
growing seasons
animals
plants

Answer: The correct answer is- light, temperature, animals, plants, topography, and growing seasons.

Habitat can be described as an area or an environment where a particular species of plant, animal or any other living organism is naturally found.

In other words, habitat is a place that supports life of a species. The presence of various biotic and abiotic factor support different habitats.

Environmental factors that create different habitats include:

  • light ( in terms of quality, time period, and intensity)
  • temperature ( such as extremely high temperature creates dry weather conditions where xerophitic plants are found).
  • topography ( study of earth surface such as mountains, valleys, rivers that support different habitats)
  • growing seasons
  • animals
  • plants
