One example of a major disturbance that almost caused a total collapse but was eventually recovered from is the Exxon Valdez oil spill in 1989. The spill devastated marine life and ecosystems in Prince William Sound, Alaska, but over time, the natural environment was able to recover due to cleanup efforts and natural resilience. Recovery efforts included wildlife rehabilitation, habitat restoration, and stricter regulations on oil transportation.

In the succession that occurs as a glacier recedes, alders can grow relatively rapidly because they are nitrogen-fixing plants, which helps improve the soil fertility by converting atmospheric nitrogen into a usable form for plants. This allows alders to colonize barren landscapes and create conditions suitable for other plant species to establish and grow.

This is known as forest succession, where abandoned fields are gradually colonized by trees and other vegetation over time. The process of regeneration and growth in these areas represents the natural progression of ecosystems in response to human activities.

The point in the body of water that is most likely to be in the aphotic zone is the deepest point. The aphotic zone is the layer of a body of water where sunlight doesn't reach, so it typically starts at deeper depths where light penetration is limited or absent.

Increasing the number of predators like lions in a zebra habitat would likely decrease the zebra population, promoting natural selection by preying on weaker or slower individuals. This could lead to a more resilient zebra population with stronger survival traits.

A climax community.

The physical environment where human communities reside can be seen as similar to a habitat in a biological community. Just as a habitat provides the necessary resources for species to survive and thrive, the physical environment of a human community offers the essential elements for its residents to live and interact. Both habitats and human communities play a critical role in shaping the lives of the organisms that inhabit them.

Many carnivores eat herbivores, which are plant eating animals, therefore no plants in turn means no food due to the starvation of the herbivores. Also there is the whole thing of plants producing Oxygen, which is required for breathing.

True. All parts of an ecosystem, including living organisms, their interactions, and the physical environment, are interconnected and interdependent. A change in one component of an ecosystem can have ripple effects throughout the entire system.

secondary succession , i had this question forr homework.

There are quite a few biotic factors that affect the size of a population in an ecosystem. Grass is one of these factors.

Unless something like bison or cows keeps the grass from growing, the forest will start growing back.

repeats in a predictable pattern over time and can affect the distribution and abundance of species within the ecosystem. Examples include predator-prey interactions, plant flowering cycles, and seasonal weather patterns. These disturbances play a critical role in maintaining the overall balance and function of the ecosystem.

Being a citizen of a community typically implies that you have specific rights and responsibilities within that community, such as participating in decision-making and governance. Being a member of a community, on the other hand, may simply signify that you belong to or are a part of that community without the same level of participation or involvement in its affairs.

Things that aren't living, like rocks, sand or weather.

The superior competitor is likely to outcompete the other species for resources, leading to a decrease in the population of the inferior competitor. This could potentially lead to the inferior competitor being displaced or evolving to occupy a different niche to reduce competition.

A natural disaster like a wildfire or volcanic eruption is most likely to trigger secondary succession. These events can wipe out existing plant and animal life, creating a blank slate for new species to colonize and establish themselves.

I have committed to volunteer regularly at local charities, participate in community cleanup events, and support small businesses in my area.

loss of habitat

Secondary succession occurs faster than primary succession because the soil already has a base of nutrients, microorganisms, and seeds left behind by the previous ecosystem. This allows for a quicker establishment of vegetation and a more rapid progression through the stages of succession.

break down organic matter into simpler nutrients that can be recycled back into the soil, making those nutrients available for other organisms in the ecosystem. This decomposition process also helps to clean up dead plant and animal matter, preventing an accumulation of waste that could harm the ecosystem.
