10. Climate change may bring warmer temperatures to a particular ecosystem.Which of the followin likely results from a warmer climate? a. Deciduous trees, like oak trees, will drop their leaves sooner. b. Some plants may bloom earlier than usual. c. Animals will hibernate longer and be less active. d. Polar bear habitats will increase in size in Earth's polar regions.

## Step 1<br />The question is asking about the potential impacts of climate change on ecosystems. Climate change can lead to a variety of changes in ecosystems, including changes in the timing of biological events such as flowering and hibernation.<br /><br />## Step 2<br />Option a suggests that deciduous trees, like oak trees, will drop their leaves sooner. However, this is not necessarily true. The timing of leaf drop in deciduous trees is primarily determined by the length of daylight and temperature, not necessarily the temperature itself.<br /><br />## Step 3<br />Option b suggests that some plants may bloom earlier than usual. This is a plausible outcome of climate change. As temperatures rise, plants may bloom earlier than usual, which could disrupt the timing of other biological events in the ecosystem.<br /><br />## Step 4<br />Option c suggests that animals will hibernate longer and be less active. This is not necessarily true. The timing of hibernation in animals is primarily determined by the length of daylight and temperature, not necessarily the temperature itself.<br /><br />## Step 5<br />Option d suggests that polar bear habitats will increase in size in Earth's polar regions. This is not necessarily true. As temperatures rise, polar ice is melting, which could lead to a decrease in polar bear habitats.
