Changes in niches can occur due to factors beyond the control of organisms, such as fluctuations in temperature, variations in water levels, or events like meteorite hits.
he paragraph mentions several reasons for changes in niches in the ecosystem. Some of these reasons include:
1. Temperature Fluctuations: The paragraph suggests that temperatures on Earth can change, either increasing or decreasing. This change in temperature can have a significant impact on the environment and the niches that organisms occupy.
2. Variations in Water Levels: Water levels in ecosystems can vary, affecting the habitats and niches of different organisms. Changes in precipitation, river flow, or sea levels can alter the availability and characteristics of aquatic environments.
3. Meteorite Hits: The paragraph briefly mentions meteorite hits as another factor that can lead to changes in niches. Large-scale events like meteorite impacts can cause widespread environmental disruptions, affecting the conditions in which organisms live.
These factors highlight the dynamic nature of ecosystems and the potential for environmental changes that can influence the suitability of niches for different populations of organisms.
