How are chemotaxis and phototaxis different?

Chemotaxis is attractiont to chemicals & phototaxis to light

What is photo kinesis?

The non-directional movement of organisms in response to light.

is a regularly repeated return journey., movement between two habitats, usually over long distances, movement of a species from two habitats on a regular basis

What is a NOT a benefit of migration?

travelling a long distance using stored energy

Ability for animal to return home after being displaced

A kinesis is an innate behavioural mechanism. But how does it work?

Rate of movement increases when in unfavourable conditions.

Which is NOT an adaptive advantage of taxes and kinesis:

move into an area that has less resources

Navigation is more accurately defined as:

being able to direct yourself from one place to another

What is meant by kinesis

Undirected movement of a cell/organism in response to an external stimulus

long term travel a regular movement, usually occurs annually

Which is an example of geotaxis?

Insects burrow down into soil when disturbed

What is one advantage of animal migration?

Favorable temperatures, Increasing the chance of survival for their offspring, A better food supply

Movement away from or towards current

returning to a home base after a short journey
