Explain how/why abiotic factors are important if this is a BIOlogy course? Consider the following to get you thinking…a) Think back to our focus on evolution and natural selection : Explain how abiotic factors, such as temperature, resource availability, soil composition, etc. affect biotic interactions in ecosystems. b) Think back to what you know about food chains and food webs from elementary school...How do you see abiotic and biotic tying in to them?

Aseries of connections of food chain in an ecosystem is called a what

Female luna moths (actias luna) attract males by emitting chemical signals that spread through the air. a male hundreds of meters away can detect these molecules and fly toward their source. the sensory organs responsible for this behavior are the comblike antennae visible in the photograph shown here. each filament of an antenna is equipped with thousands of receptor cells that detect the sex attractant. based on what you learned in this chapter, propose a hypothesis to account for the ability of the male moth to detect a specific molecule in the presence of many other molecules in the air. what predictions does your hypothesis make? design an experiment to test one of these predictions.
