Analyze how rising temperatures due to global warming affect the population size of:o Tall deciduous trees

1. Increased Temperature: Rising temperatures due to global warming can have a direct impact on the growth and survival of tall deciduous trees. These trees thrive in moderate temperatures. If the temperature rises beyond their tolerance level, it can lead to heat stress, causing damage to the tree's cellular structure and metabolic functions. This can lead to reduced growth and even death of the trees, thereby reducing their population size.

2. Changes in Precipitation: Global warming also affects the patterns of precipitation. It can lead to either excessive rainfall or prolonged periods of drought. Both these conditions are not favorable for the growth of tall deciduous trees. Excessive rainfall can lead to waterlogging, which can suffocate the roots and lead to the death of the trees. On the other hand, drought can lead to water stress, causing the trees to wilt and die. This can also lead to a decrease in the population size of these trees.

3. Increased Pest and Disease Incidence: Rising temperatures can also lead to an increase in the incidence of pests and diseases. Many pests and disease-causing organisms thrive in warmer conditions. This can lead to an increase in the incidence of pest attacks and diseases in tall deciduous trees, leading to a decrease in their population size.

4. Changes in Growing Seasons: Global warming can also lead to changes in the growing seasons. It can lead to earlier springs and later autumns. This can disrupt the growth cycle of tall deciduous trees, affecting their ability to grow and reproduce, thereby affecting their population size.

5. Impact on Pollinators: Many tall deciduous trees depend on certain species of birds and insects for pollination. Changes in temperature can affect these species, which can in turn affect the reproduction of the trees, leading to a decrease in their population size.

In conclusion, rising temperatures due to global warming can affect the population size of tall deciduous trees in multiple ways. It can directly affect their growth and survival, and can also have indirect effects through changes in precipitation, increased pest and disease incidence, changes in growing seasons, and impacts on pollinators.
