Explain how invasive species can alter the food web in an ecosystem.

Answer explanation

Invasive species can alter the food web by outcompeting native species for resources, disrupting the balance of predator-prey relationships, and introducing new diseases or parasites that affect other organisms.

(a)   is a strategy to mitigate the impact of invasive species.

• Ignoring the problem
• Introducing more invasive species
• Implementing biological control
• Increasing pollution

Answer explanation

Implementing biological control is a strategy to mitigate the impact of invasive species by introducing natural enemies to control the invasive species population.

Predict how the introduction of an invasive predator might affect the population of native herbivores in an ecosystem.

Answer explanation

The introduction of an invasive predator would likely decrease the population of native herbivores due to increased predation and competition for resources.

Describe one way in which invasive species can disrupt the flow of energy in an ecosystem.

Answer explanation

Invasive species can disrupt the flow of energy in an ecosystem by outcompeting native species for resources, leading to imbalances in the food chain.

Match the following impacts of invasive species with their descriptions: - Competition - Predation - Disease introduction

Answer explanation

The correct match is Competition - 1. Invasive species can outcompete native species for resources, leading to negative impacts on the ecosystem.

What is one method used to predict changes in an ecosystem due to invasive species?

Answer explanation

One method used to predict changes in an ecosystem due to invasive species is through ecological modeling, which simulates the potential impacts of the invasive species on the ecosystem.
