Good question..

CO2 can still diffuse out of plant tissue when stomata are closed at night plus plants can reduce their metabolism to reduce the rate of respiration during the night.

To reproduce and pass your genetics on to the next generation

To be happy

To exist

You will definitely have some skills from your computer science degree that would be very useful in terms of modelling and what not in ecology and biology. If it is enough to jump into a masters degree in one of these fields I'm not sure. You might have a better chance of doing a graduate diploma or...

Don't really see what you're talking about with the shadows. It doesn't really look like anything has a shadow to me, as if it is just an overcast day. The photo does look weird though.

The difficulty with the concept of innate ideas or innate behaviors is that it is difficult to prove every potential environmental factor did not cause the observed behavior. For example, showing that chicks react to bird-like shapes above them doesn't prove that another factor did not previously le...

Forests are important for a whole heap of reasons and not just from an ecological perspective. In addition to what people have already said (maintain biodiversity, cleaning air and water, producing oxygen) they provide habitat for a heap of birds, mammals and invertebrates, they provide food, timber...

Do plants require the presence of oxygen to heal wounds?

If you know anything about this or know of any literature on this topic, I would appreciate any information. I have had a quick look but haven't had much luck finding anything.

In the recent series "Cosmos" with Neil deGrasse Tyson, he seems to think that the most likely origin of life is from comets. Interesting when you consider that not long ago the general consensus was that it was unlikely that any life existed other than that on Earth..

But what it you draw the line at chicken and don't look at the ancestors of a chicken. The chicken came from an egg, the egg came from an ancestor that was slightly different to a chicken but wasn't a chicken, but the chicken still came form an egg.

Yep that's pretty much it. A lake within a forest is two different ecosystems and the same goes for a river running through rainforest. The boundaries of an ecosystem are basically defined by different types of environments, so the size of ecosystem is governed by how large the area is where the env...

Going off the information you've given: A) The acceleration phase is the initial increase in population and is often followed by an exponential growth phase (if conditions continue to be favourable), similar to what the human population has been going through. If a population is small enough, the re...
