Can a impact in one species over time can impact an ecosytem ?

Yes

Explanation:

Yes, the impact on one species over time can impact ecosystem.

An ecosystem is consist of biotic and abiotic organisms. There is a major relationship between biotic and abiotic or biotic and biotic components.

The relationship between biotic and biotic components is called food chain, in which one organisms depends on others for their survival and balance the energy flow in the ecosystem. So impact on any one species in the food chain will impact the whole ecosystem.

For example: Plants are the producers in the food chain, and if plants will be impacted or destroyed over time, the consumers depending on the plants will die from starvation and disturb the energy flow in the ecosystem. Along with this, plants are also related to abiotic factors such as maintenance of oxygen and carbon dioxide in the atmosphere, so the balance of these gases will also get disturbed.
