Answer: Option B and C.
Heavy and continuous rains flood the land, submerging habitats.
c. Lightning strikes a tree and begins a fire that clears the land.
Explanation:
Heavy and continuous rains flood the land, submerging habitats.
Lightning strikes a tree and begins a fire that clears the land.
The above are example of density independent abiotic factors because rainfall and lightning affect the population size of the environment by decreasing it's population sizes.
Abiotic factors are the non living part of the environment and they include rain fail, temperature,lightning, humidity e.t.c.
Density independent abiotic factors are factors that decrease or increase the population size of the ecosystem.
Therefore, Heavy and continuous rains flood the land, submerging habitats.
cLightning strikes a tree and begins a fire that clears the land are density independent factor because they decrease the population size.
The scenarios that describe an abiotic factor that is density independent are ; ( B and C )
Abiotic factors are Nonliving components of an ecosystem that has a significant effect on the ecosystem such as ; Rain, rocks, Temperature and humidity. Density Independent factors are factors in an ecosystem that can cause the decrease or increase of the population size of an ecosystem.
Heavy and continuous rainfall is an abiotic factor that has the ability to decrease the population of an ecosystem by submerging organisms habitats.
Lightning striking a tree and setting it ablaze which clears the land also reduces the population of the ecosystem because the fire will lead to loss of habitats and death of some organisms .
Hence we can conclude that The scenarios that describe an abiotic factor that is density independent are Heavy and continuous rains flood the land, submerging habitats and Lightning strikes a tree and begins a fire that clears the land .
