Question,
How might a food web that includes a consumer that is a threatened species (in low numbers) be affected if the consumers population continues to decline?
A food web that includes a consumer that is a threatened species can be affected if the population continues to decrease by not having a consumer to eat the organism before them. This can be a 1st degree consumer, or 1st degree producer. Since there would be no organism to eat the other, this would mean that the consumer would increase in growth and population to an extent where it’d get bad and affect the ecosystem. As well, if the consumers population declines this means the consumers beyond their level would not have much to eat.
Story
Once upon a time there was a Barred owl named Katherine. Katherine loved to adventure; she’d spread her wings high and go to places she’d never been before. One day, she found herself in a city called Port Coquitlam, located in a temperate rain forest of British Columbia. Katherine is an Apex Predator. This means that she has no natural predator. Because Katherine is an apex predator, this makes her be at the top of her food chain(s).
As a small owl, Katherine used to go with her mother in the nest. There she learned how to fly and picked up many characteristics such as hunting for prey from her mother. She’d hunt at night, and sleep in the day. Katherine loved to hunt for animals such as small rodents and mammals. Because Kathrine enjoyed eating this animals, she actually helped crop land and other type of lands being ruined by these rodents. Like other owls, Katherine is awake at night and falls asleep in the daytime.
Since Katherine would play a big role in the environment as an owl, she also interactions with the earths 4 spheres. These are the Atmosphere, Hydrosphere, Biosphere, and Geosphere. When it comes to the Atmosphere, naturally Katherine is an owl and can fly. The way she interacts with the atmosphere is by flying places, not all animals can do this. With the biosphere, she likes to eat small rodents, and with the Geosphere she could naturally pick up sticks to make a nest for her children.
That is the story of Katherine. Humans never minded since she captured prey at night and slept in the day after a big feast. Katherine never moved out of Port Coquitlam, or Bc, in fact she lived happily ever after.
