Trees have several niches in a forest. Describe what they are.
Air, homes, carbon cycle, food, soil.
If the number of snakes in this food web decreases, what will happen to rabbits and hawks at first.
Hawks will decrease rabbits will increase
If the pine trees are the main habitat for the birds, what will most likely happen to their population if a construction company were to come in and clear a significant number of the trees? How would it also effect the number of insects and owls? Support.
Birds would die or eave because of no home then the owls would decrease because of limited food. Insects would increase.
If the population of owls decreased, would the Lynx population be greatly affected? Why or why not?
The lynx population wouldn't be greatly affected because of its other food chains.
If the elk and moose population were reduced because of hunting, how would the wolf population be affected? Explain.
The wolf population would decrease greatly because of limited food.
Thinking about the concept of biodiversity, which consumer in the food web would LEAST likely be affected of one of their food sources was lost to disease. Support.
Lynx because it has many food groups.
What are the secondary consumers in this food web?
Name the producers in this food web.
If their is an increase in the number of lynx, how will that affect the number of fox and eventually the number of mice in the ecosystem?
They would eat the fox all up ad mice would increase a lot!
the lynx is several kinds of consumers in this web. Name them.
Using this web, create a food chain that includes the owl.
What do all food chains begin and end with.
What organism feeds on an and all levels of the energy pyramid?
Is fungus considered a producer or decomposer? Defend your answer!
Decomposer it eats any and all levels of the energy pyramid.
What is the difference between decomposer and scavenger?
