Ecosystems are an integrated process that requires each part to be present to allow the whole system to operate correctly. This is similar to a car engine that requires all of its parts to work - "over removing" the crankshaft affects the whole engine.In the case of fish they are both consumers and consumed. Fish eat smaller plants and animals that would overpopulate their niche in the ecology if not removed. This ould cause a depletion of the smaller plants and animals they feed on crating a barren base ecology. As fish are consumed, the animals they feed would be starved for food and either die out or move to other locations. They might also switch to less nutritious food or to species that are not as numerous and deplete their numbers.
It doesn't stop there. Bears, as an example, eat salmon. They then wander through the woods where their faces provide nutrients for trees. The trees provide ecologies for a wide range of animals and have other functions like soil building with their leaves or needles and soil stabilization with their roots. Therefor - no salmon, no bears, no healthy trees, no birds and squirrels, no control of erosion, eroded soil fills the streams and the hydrogeology of the ecosystem changes.

How could overfishing lead to ecosystem collapse?
many mammals rely on fish for food
How do daily human activities affect the ecosystem?
Daily human activities such as deforestation, pollution, and overfishing can have detrimental impacts on the ecosystem by destroying habitats, polluting water and air, and depleting natural resources. These activities can lead to loss of biodiversity, climate change, and other environmental problems that can disrupt the balance of the ecosystem.
Why might an overfishing of herring lead to an increase in populations of sea urchins?
An overfishing of herring can disrupt the food chain and remove a key predator of sea urchins. With fewer herring to feed on sea urchins, their populations can increase unchecked leading to ecosystem imbalance and potentially to overgrazing on kelp forests where sea urchins feed.
What is some things human do to destroy your ecosystem?
Humans destroy ecosystems by deforestation, polluting air and water, overfishing, and introducing invasive species that disrupt the balance of the ecosystem.
Predict what will happen if there are no decomposers?
If there are no decomposers, dead plant and animal matter would not be broken down and recycled back into the ecosystem. This would lead to a buildup of organic material, resource competition, nutrient deficiencies, and ultimately ecosystem collapse. The cycle of nutrients would be disrupted, negatively impacting the balance of the ecosystem.
How easily can a food chain collapse?
A food chain can collapse relatively easily due to various factors such as environmental changes, habitat destruction, overfishing, pollution, or the introduction of invasive species. Disruption at any level of the chain, like the decline of a keystone species, can have cascading effects throughout the ecosystem. Additionally, climate change can alter food availability and species interactions, further destabilizing food chains. Such collapses can lead to significant biodiversity loss and disrupt ecosystem services.

What does overfishing look like?
Overfishing occurs when fish are caught at a rate faster than they can reproduce, leading to a decline in fish populations. This can result in empty nets for fishermen, diminished biodiversity, and the collapse of marine ecosystems. Indicators of overfishing include smaller catch sizes, the prevalence of juvenile fish in catches, and changes in species composition. Additionally, it can lead to increased competition for dwindling resources and negative impacts on coastal communities that rely on fishing for their livelihoods.

What are the methods of fishing that disturb the interrelationshipin an ecosystem?
Some methods of fishing that can disturb the interrelationship in an ecosystem include bottom trawling, which can destroy habitats on the seafloor, and using large nets that result in bycatch of non-target species. Overfishing can also disrupt the food chain and lead to imbalances in populations within the ecosystem.
What will happen if wolves become extinct?
There will be no more wolves and the ecosystem will collapse some.
Which renewable resources can become nonrenewable if mismanaged?
Renewable resources such as water, forests, and fisheries can become nonrenewable if mismanaged. Overextraction of water resources can lead to depletion of aquifers, deforestation can result in irreversible loss of biodiversity and ecosystem services, and overfishing can collapse fish populations. Sustainable management practices are essential to ensure these resources remain viable for future generations. Without careful stewardship, these resources may not regenerate at a rate that meets human demands.
What unsustainable use of natural resources?
Unsustainable use of natural resources refers to practices that deplete or degrade resources faster than they can naturally replenish. This includes activities like overfishing, deforestation, and excessive groundwater extraction, which can lead to biodiversity loss, ecosystem collapse, and long-term environmental harm. Such practices threaten the balance of ecosystems and can compromise the ability of future generations to meet their needs. Transitioning to sustainable practices is essential for preserving these resources for the future.
