Question

Natural selection lab

to simulate the mechanism of natural selection from predation. to understand of the concept of natural selection and its relation to ecology. learn how models can help with understanding evolutionary principles.

first generation 25beans 50 coins 25 rice the bird predator using the fork sweeps down and eats on the carpeted habitat for 10 seconds then stops eating. bird predators can only scoop up the prey with the fork-on- hands and only pick up one insect at a time.

please answer following questions at least 5 sentences detail

1 what if there was another type of bird predator that had a spoon-beak? how might the presence of a spoon-break bird predator change the frequency of insect phenotypes over time?

2 in the exercise we kept the habitat, the carpet, constant. but imagine if the habitat that the bean, rice and coin insects lived in changed in such a way that the coin insects were camouflaged now and difficult to see, but the beans and rice insects were not camouflaged and stuck out like a three phenotypic frequencies of the insect population?

using word environment and adaptation

Answer 1

1.A spoon-beaked predator is expected to scoop up the prey from the carpeted habitat with its beak. It does not require it's fork on the hands to scoop out the prey. So a spoon-fed beaked bird can feed itself for longer than 10 seconds. It can take in any shape of the insect with ease.

Since coin shaped insects are twice as bean and rice shaped insects it is expected that probability of eating coin shaped insects will be more.So over a period of time the number of all the insects might be more or less equal.

2. In the event when coin shaped insects have adapted to the danger of being eaten by birds and are camouflaged, the bird will eat bean and rice shaped insects only. Thus coin shaped insects will survive in such environment and eventually out number the other two which might get extinct if it is a small population.
