Distribution of Organisms And Enviromental Factors

If you can remember primary school you probably already know this topic. But if, like me, you have the memory of a goldfish, then you might need some revising.

First things first:

Why?

Why bother collecting organisms? So you know where they live! That's about it to be honest...

The face things:

1. Pooters

These are little beakers with tubes and a gauze. You suck into a tube and the other tube, preferably the one without the gauze on, sucks the insect up. The gauze on your side stops you being bugged... Get it? I'm sorry.

    2.  Pitfall traps

It's a pit... they fall into... See the diagram:

    3. Sweep nets

A net with a strong cloth that is used to collect insects and spiders and stuff from long grass.

    4. Pond Nets

Used for collecting things from... ponds...

Quadrats

Bit more to remember on these! Basically all you need to know is count the organisms you see in your quadrat then do it again with somewhere else so the same ones don't sneak in. Then learn this:

"MEAN = TOTAL NUMBER OF ORGANISMS/ NUMBER OF QUADRATS

Enviromental Factors

You can do these things to measure them, all you need to know:

1. Use a thermometer to measure the temperature in different places
2. Use a light sensor for light intensity
3. Measure soil PH using indicator liquid. Acid soil? What next!
