Look at the food web shown below. Which organisms get energy from producers?
The food web consists of an arrow going from a phytoplankton to a zooplankton to a shrimp to a squid to a sperm whale.
squid
zooplankton
sperm whales
phytoplankton
The zooplankton, shrimp, squid, and sperm whale get energy from the producers (phytoplankton) in this food web.
only choose one
Zooplankton gets energy from producers (phytoplankton) in this food web.
some people have attached ear lobes and some people have free ear lobes. The differences in these traits are caused by:
There is an image that provides what an attached ear lobe and a free ear lobe looks like.
a. differences in environment
b. differences in personality
c. differences in diet
d. differences in genes
d. differences in genes
The differences in attached vs. free ear lobes are caused by genetic variations.
Relationships between organisms may be beneficial or detrimental. Which of the following examples shows a relationship in which both organisms benefit?
a. a tick attaches itself to the skin of a dog and takes a blood meal
b. a female black widow spider, Latrodectus mactans, mates with a male spider, then, she consumes him
c. an African wasp Ceresolen arabicus pollinates a fig tree ficus sycomorus as it eats the tree's nectar.
d. A species of hyena known as the aardwolf consumes termites for nourishment
c. an African wasp Ceresolen arabicus pollinates a fig tree ficus sycomorus as it eats the tree's nectar.
In this case, both organisms benefit from the relationship - the wasp gets food (nectar) from the tree, and in the process, it pollinates the fig tree, aiding in its reproduction.
The Canadian lynx is a large wild cat that lives in the cold regions of Canada. The snowshoe hare is the main prey species that is hunted by the Canadian lynx. The snowshoe hare eats grass, fern, and leaves. If the population of Canadian lynx were to completely disappear, what would most likely happen to the food supply of the snowshoe hare?
the population of snowshoe hare would decrease, and there would be more food available
the snowshoe hare would stop eating grass, so there would be less food available.
the snowshoe hare would start eating each other, so the food supply would not be affected
the population of snowshoe hare would outgrow the food supply, so there would be less food available.
the population of snowshoe hare would outgrow the food supply, so there would be less food available.
If the Canadian lynx completely disappeared, the population of snowshoe hares would likely increase rapidly due to the removal of a major predator. This increased population would put strain on their food sources (grass, ferns, and leaves), leading to a decrease in the available food supply for the hares.
a new predator is introduced into the ecosystem shown in the food web below. This predator feeds on bees and mice. How will this most likely affect the species in this ecosystem.
The food web consists of a mouse having a plant that has arrows pointing to a fox, a mouse, a bee, and a black bear. The bee has an arrow pointing towards the black bear, and the mouse has an arrow pointing to the fox.
There will be a decrease in bees and mice which will cause an increase the black bear population and a decrease in the fox population.
There will be an increase in bees and mice which will cause an increase in the populations of both black bears and foxes
There will be an increase in bees and mice which will cause a decrease in the black bear population and an increase in the fox population
There will be a decrease in bees and mice which will cause a decrease in the populations of both black bears and foxes.
