Question

in three to five sentences explain with evidence on how changes to physical parts of an ecosystem change its population.

Answer 1

Changes to physical parts of an ecosystem, such as alterations in climate, habitat destruction, or the introduction of pollutants, can significantly impact species populations. For instance, deforestation reduces habitat availability for many species, leading to decreased populations as animals struggle to find shelter and food. Similarly, temperature changes due to climate change can shift the distribution of species, such as shifting fish populations toward cooler waters, which can disrupt existing ecological balances. Studies have shown that ecosystems under stress from pollution often experience reduced biodiversity, ultimately leading to population declines among sensitive species. This evidence underscores the interconnectedness of physical ecosystem elements and biological communities.
