Homework   Due on the Week of March 14

(In celebration of Women’s History Month)

In the past, women were being looked down on, and not given the recognition that they are capable to succeed.  It is possible that this type of bias is still taking place today.    

Pick a female scientist.  Pretend that she is a good friend who is writing a letter to you.  ==================================================================

In the letter, include the following:

Ø  A challenge that your friend (the female scientist you picked) must have experienced to succeed.  (This part is made up based on what you believe must have happened)

Ø  How your friend overcame the challenge.  (Example:  her dedication and commitment)

Ø  The discovery made by your friend.  (Include her joy and pride)

Q5) Why does it make sense to call the animals, ‘consumers’? They have to work for their food. 
Q6) Define, “primary consumers”: _____Animals who only eat plants_____________ 
Q7) What other name is given for the primary consumers? _______Herbivores__________ 
Q8) Define, “secondary consumers”: _____________Animals who eat other animals
 Q9) What other name is given for the secondary consumers? ____Carnivores____________ Q10) Define, “omnivores”: ____Animals who eat both plants and meat_____ 
Q11) Which category do you fit in?____Answers vary_________________________________

 Q16) A bird from South America is accidentally released into the community. This bird is excellent at hunting spiders. What will happen to the local populations of insectivorous birds (birds who eat insects)? Insectivorous (insect eating) birds eat spiders for food. If spiders get eaten by the other bird, the number of insectivorous bird will decrease (get smaller). 
 Q17) A viral infection (sickness) destroys the fox population. Explain how will this affect the hawk population? Hawks and foxes compete (fight) for the same foods. If foxes decrease in their number, hawks will have more foods to eat and will increase (get larger) in their population (number). 
 Q18) Due to weather changes, the populations of predaceous insects (insects that eat other insects) migrates (move) to a different habitat (location). Explain how this will affect the plant population. Predacious insects eat herbivorous insects. Herbivorous insects eat plants. If the populations of predacious insects decrease, the number of herbivorous insects increase, and the population of plants will decrease as the herbivorous insects will start eating up more of the plants.
 19) Drought leads to reduction of plants. Explain how this can affect the entire food web. The decrease in the populations of plants be a disaster for the whole animals of food web. The 1st level of consumers depend (need) plants as their food. The 2nd level of consumers depend on plants as their food.
