Ah, I see. All the diagram shows is how many of each animal there is. Not if they interact with each other in any way. So there is no way to conclude if they form a community. But how would I conclude that the plant is a habitat of the organisms? Because it was mentioned that the observation was...

Its defined as 2 or more populations living together in the same habitat and interacting with each other as well as their surroundings.

Sorry didn't realize the photo was tilted. Will upload a new copy once I'm back home.

Homework Statement http://i41.tinypic.com/1079dsk.jpg This is the given question for a grade 6 student during his exams. I was asked to provide an answer for him but I have a few doubts. Homework Equations None The Attempt at a Solution I know that option B is definitely wrong...

Thank you mfb and Basic_Physics. Answered my question!

@CWatters The problem is the solution requires me to only draw to rays from point X. So I cannot draw addition rays from point X or any other rays from any other point of the needle. Only 2 rays from X are allowed. So I don't understand why the image is the same size as the object.

Homework Statement This is the given question. The blue rays represent the solution. http://img16.imageshack.us/img16/7237/lenstq.jpg Homework Equations None. The Attempt at a Solution The blue rays are essentially my solutions, but only up to the point where the rays are...

So in other words the distances are insignificant when compared to our size?

As you can see from the title, I'm puzzled as to what occupies the spaces in between the particles in a gas. Take air for example. In Chemistry, I have learned that the particles in a gas are far apart. Hence the particles in the air around me are far apart. But if there are no particles in...

Hi guys needed to check up on something. Recently in school we were taught that in order to test for the presence of chloride ions, we had to add acidified silver nitrate to check for the precipitation of silver chloride. Similarly, to test for sulfates, we were told to add acidified barium...
