Besides that, all good. Your go.

Re: Ecology B/C
Correct, however all of that is interrelated. For example, the lack of food in the winter is due to the colder temperatures (as it's winter) and the drought is due to higher temperatures (as it's summer.) So, it's fair to say that both estivation and hibernation are states of prolonged torpor caused by (to some degree) extreme temperatures, and not only high temperatures, as chscioly put it.gavinnupp wrote:According to Wikipedia, estivation is in response to hot and dry conditions (to avoid losing moisture or damage from temperatures) while hibernation occurs in warm-blooded animals when their isn't gonna be enough food.Zioly wrote:All correct, save a few minor inaccuracies.

That's how I viewed it, but I do see that most sources are saying hibernation as a response to lack of food (presumably ignoring temperature) and estivation as temp and precip. I'll put that down as something to look into later on the internet. I'm primarily referring to one source, so I might not have the most universal information right off the bat.

Anyone can feel free to go. I'm itching to answer some questions.

Name at least two adaptations used by plants in the tundra.

Plants in the tundra grow close to the ground and in clumps to protect against the cold.Sensei_Sushi wrote:Name at least two adaptations used by plants in the tundra.
Plants are inactive for 9 months, to wait for the annual thaw of the active layer.
The roots of these plants are adapted to growing sideways, as they can't penetrate the permafrost below.

Re: Ecology B/C
Close, it should be around 14 years, depending on which way you found the answer.LIPX3 wrote:chscioly wrote:If a population has an annual growth rate of 5%, what is the doubling time?15 years

Re: Ecology B/C
Correct! Another could be that they adapt to conducting photosynthesis in low temperature levelsZioly wrote:Plants in the tundra grow close to the ground and in clumps to protect against the cold.Sensei_Sushi wrote:Name at least two adaptations used by plants in the tundra.

In order to resolve the two ongoing threads, we can start with whoever provides a question first (Zioly or LIPX3) if that's alright.
