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.
Why can overfishing The of an ecosystem is based on whether the population in the system destroys the natural resources of that system.lead to ecosystem collapse?
Overfishing disrupts the balance of marine ecosystems by depleting key fish populations, which can lead to the overgrowth of their prey and the decline of species that depend on them. This imbalance can trigger a cascade of negative effects, affecting biodiversity and the overall health of the ecosystem. As essential species dwindle, the ecosystem's ability to recover diminishes, ultimately leading to collapse. Such collapses can result in irreversible damage, affecting not only marine life but also human communities reliant on these resources.
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.

Human activities interfere with food chain and food web in the ecosystem?
Human activities, such as deforestation, pollution, and overfishing, significantly disrupt food chains and food webs within ecosystems. Deforestation can lead to habitat loss, affecting species populations and their interactions. Pollution introduces harmful substances that can accumulate in organisms, impacting their health and reproduction. Additionally, overfishing can deplete key species, causing imbalances that ripple through the entire ecosystem.
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 is the practice of harvesting fish faster than they can reproduce is called?
The practice of harvesting fish faster than they can reproduce is called overfishing. This unsustainable practice depletes fish populations, disrupts aquatic ecosystems, and can lead to the collapse of fisheries. Overfishing threatens not only the species being targeted but also the livelihoods of communities that depend on fishing. Effective management and conservation efforts are essential to prevent overfishing and ensure the long-term health of marine resources.

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.
