Explain why understanding carrying capacity is important in ecology.

Carrying capacity is important for managing and conserving natural resources, predicting population dynamics, and making informed decisions for sustainable development.
Carrying capacity is only relevant for small-scale ecosystems
Understanding carrying capacity is only important for urban planning
Carrying capacity has no impact on ecology

Describe how the carrying capacity of an environment can be affected by human activities.

Human activities can reduce the carrying capacity of an environment.
Human activities have no impact on the carrying capacity of an environment.
Human activities always increase the carrying capacity of an environment.
Carrying capacity is not affected by human activities.

MULTIPLE CHOICE QUESTION

Give an example of a real-world ecosystem and explain how its carrying capacity might have changed over time.

A desert ecosystem; due to factors such as excessive rainfall, overpopulation of herbivores, or lack of predators.
An ocean ecosystem; due to factors such as pollution, overfishing, or introduction of invasive species.
A grassland ecosystem; due to factors such as extreme weather events, decrease in herbivore population, or natural disasters.
A forest ecosystem; due to factors such as climate change, deforestation, introduction of new species, or human activities.

MULTIPLE CHOICE QUESTION

Imagine a scenario where a population of deer exceeds the carrying capacity of its habitat. Predict what might happen to the deer population and the ecosystem as a whole.

The deer population will increase due to abundance of food and resources
The deer population may decline due to lack of food and increased competition for resources, leading to habitat degradation and disruption of ecological balance.
The ecosystem will become more balanced and stable
The deer population will migrate to a new habitat and thrive

Explain the difference between exponential growth and logistic growth in the context of population growth models.

Exponential growth is limited, while logistic growth is unlimited.
Exponential growth is unlimited, while logistic growth is limited by carrying capacity.
Exponential growth is affected by carrying capacity, while logistic growth is not.
Exponential growth occurs in a closed system, while logistic growth occurs in an open system.

A population of rabbits in a forest ecosystem has an initial population of 100 rabbits. The carrying capacity of the forest is estimated to be 1000 rabbits. The population of rabbits grows at a rate of 0.1 per year (10% growth rate). Calculate the population size after 5 years using the logistic growth model.
