Question

Select the correct answer from each drop-down menu. Complete the paragraph based on this food chain: flowchart of ecosystem food chain. Five boxes slanting towards the left, from top to bottom are labeled polar bears, seals, herring, small fishes, plants. Each box from below to upward is shown with an upward pointed arrow. Polar bears feed on seals. So, polar bears and seals share a ________. Climate change has caused ice caps to melt in colder regions where polar bears live. This change has made it harder for polar bears to successfully hunt seals. This situation will lead to ________.

1) Predator-prey relationship, Decrease in polar bear population
2) Symbiotic relationship, Increase in polar bear population
3) Competition, Increase in seal population
4) Mutualism, Decrease in seal population

Answer 1

Polar bears and seals share a predator-prey relationship, and the melting of ice caps due to climate change will result in a decrease in polar bear population.

Step-by-step explanation:

Polar bears and seals share a predator-prey relationship. Due to climate change and the melting of ice caps, it has become harder for polar bears to hunt seals, leading to a decrease in polar bear population.
