What are some changes in the ecosystem that can disrupt its balance?
Natural events, such as extreme weather, flooding and natural hazards can disturb the balance of ecosystems. For example, in 1987, a great storm resulted in the felling of 15 million trees in England. This led to a considerable decline in primary and secondary consumers in the food chain.
What are some environmental factors that can cause changes in ecosystems?
Important direct drivers include habitat change, climate change, invasive species, overexploitation, and pollution. Most of the direct drivers of degradation in ecosystems and biodiversity currently remain constant or are growing in intensity in most ecosystems (see Figure 4.3).
What are 4 environmental changes?
Major changes such as land subsidence, climate change, habit alteration, water quality, population growth, water exports, invasion by nonnative species, and in-delta physical changes will continue to change the delta during the current century and beyond.
What might disrupt a stable ecosystem?
Ecosystems change over time. Sudden disruptions such as volcanoes, floods, or fires can affect which species will thrive in an environment. Other disruptions are caused by human activities. … These changes influence a community’s biodiversity and can disrupt an entire ecosystem.
What are some examples of natural disruptions to the environment?
Natural disturbances include fires, insect outbreaks, disease epidemics, droughts, floods, hurricanes, windstorms, landslides, avalanches, and volcanic eruptions. In terms of frequency and area affected, the two major natural disturbances affecting wilderness areas are fire and insect outbreaks.

The top ten environmental issues are these:
- Climate Change.
- Biodiversity and Land Use.
- Chemicals, Toxics and Heavy Metals.

How does natural environmental change affect ecosystem stability?
Climate change can alter where species live, how they interact, and the timing of biological events, which could fundamentally transform current ecosystems and food webs. Climate change can overwhelm the capacity of ecosystems to mitigate extreme events and disturbance, such as wildfires, floods, and drought.

Which event might disrupt a stable ecosystem quizlet?
Occurs when a stable and balanced ecosystem (climax community) is disturbed. This disturbance could be in the form a forest fire, flood, change in climate, volcanic eruption, or another disaster.
What human activities might disrupt a habitat?
Major Kinds of Habitat Loss
Other ways people directly destroy habitat include filling in wetlands, dredging rivers, mowing fields, and cutting down trees. Habitat fragmentation: Much of the remaining terrestrial wildlife habitat in the U.S. has been cut up into fragments by roads and development.
How does Habitat destruction affect ecosystems?
The primary effect of habitat destruction is a reduction in biodiversity, which refers to the variety and abundance of different species of animals and plants in a particular setting. When an animal loses the natural home or habitat that it needs to survive, its numbers decline rapidly, and it moves toward extinction.
