Wind, rain, predation and earthquakes are all examples of natural processes which impact an ecosystem. Humans also affect ecosystems by reducing habitat, over-hunting, broadcasting pesticides or fertilizers, and other influences.
What is one thing that can damage an ecosystem and why?
Damaged ecosystems occur when species within the system are lost, habitat is destroyed and/or the food web is affected. Pollution, over-exploitation, climate change and invasive species pose particular threats to the world’s ecosystems, biodiversity and ecological integrity.
What is one way an ecosystem can be damaged?
When we introduce external factors such as too much carbon dioxide or methane, it destroys the balance of the ecosystem which in turn affects those who live in it. The result is global warming, water shortage, extinction of species, etc. These impacts every living thing on the planet, which includes us.
What are 3 important things people get from ecosystems?
As a society, we depend on healthy ecosystems to do many things; to purify the air so we can breathe properly, sequester carbon for climate regulation, cycle nutrients so we have access to clean drinking water without costly infrastructure, and pollinate our crops so we don’t go hungry.
What are the two factors that affect ecosystems?
The environment includes two types of factors: abiotic and biotic.
- Abiotic factors are the nonliving aspects of the environment. They include factors such as sunlight, soil, temperature, and water.
- Biotic factors are the living aspects of the environment.
What causes ecosystems to transform?
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 human activities destroy the ecosystem?
Various Human Activities That Affect an Ecosystem

What are the main causes of threat to ecosystem?
Answer: Hunting and poaching by greedy hunters for commercial purpose and their profits. Pollution due to chemical and industrial waste and acid deposits. Introduction of alien species and reckless cutting of forests to bring land under cultivation.
Which is an example of a stable ecosystem?
Oceans is stable ecosystems since it stays unchanged over the long term. Various natural geological and anthropogenic forces build and damage mountains, deserts and forests but oceans have remained stable over the long history of the Earth.
