My muddiest point so far had to do with the food web. I don't understand which consumer is the primary consumer in the web. I also don't quite understand what "Niches" are.
The big thing with food webs is that you need to follow ONE chain at a time.
A food web is made of lots of different food chains.... so take it one chain at a time.
The FIRST animal to eat a producer is the primary consumer. Primary just means 'first'.
It is possible for a consumer to be both a primary consumer and a secondary consumer. Or both a secondary consumer and a tertiary consumer. Or both a tertiary consumer and a primary consumer... ETC!!! The question is... WHAT FOOD CHAIN ARE YOU FOLLOWING????
AGAIN, you NEED to look at individual food chains to answer questions about food webs.
A niche is basically an organisms role in the ecosystem. So... an organism's niche is made up of its role in the food chain (who eats it, and what it eats) AND where it physically lives.
the role of an organism within its natural environment that determines its relations with other organisms and ensures its survival. hope i helped
