Chapter 38: Problem 37

As a conservationist, you are preparing a report on a frog population living on a mountainside in Costa Rica. In your report, which potential threats to the survival of the species will you predict taking into account environmental abiotic conditions and human activities? a. The frog is at risk from climate change, habitat destruction, and aggressive predators. b. The frog is at risk from climate change, exotic species, and possible habitat destruction. c. The frog is at risk from climate change, habitat destruction, and sparse availability of food. d. The frog is at risk from climate change, exotic species, and over-hunting in its habitat.

Short Answer

Expert verified
Option c: The frog is at risk from climate change, habitat destruction, and sparse availability of food.

Step by step solution

01

- Analyze Abiotic Threats

First, consider the environmental abiotic conditions that could be affecting the frog population, such as climate change. The common threats that fall under these conditions include climate change, changes in precipitation, and temperature fluctuations.
02

- Analyze Biotic Threats

Next, evaluate the biotic threats such as the introduction of exotic species, predation by natural or invasive species, and the availability of food. These threats impact the frog's ability to survive and reproduce.
03

- Evaluate Human Activities

Consider how human activities like habitat destruction and over-hunting could threaten the frog population. These activities often result from deforestation, urbanization, and agricultural expansion.
04

- Compare Choices

Compare the given options with the identified threats. Identify which option includes all the threats discussed.
05

- Choose the Best Option

Option c lists climate change, habitat destruction, and the availability of food. These align with both abiotic conditions and human activities, which are significant to the frog鈥檚 survival.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Climate Change Effects
Climate change significantly impacts frog populations. Changes in temperature and precipitation patterns can disrupt their breeding cycles and habitat conditions. Frogs rely heavily on specific temperature ranges and moisture levels for their survival.

As global temperatures rise, the delicate balance within frog habitats is altered. Unusual weather events such as droughts can reduce water availability, while increased rainfall can lead to habitat flooding. Both scenarios can decrease the frogs' chances of survival and reproduction.
Habitat Destruction Impact
Habitat destruction poses a severe threat to frogs. Activities like deforestation, urbanization, and agricultural expansion lead to the fragmentation and loss of natural habitats.

Frogs need specific environments to thrive, and when these environments are destroyed or altered, it becomes challenging for the frogs to find shelter, breed, and find food. The fragmentation of habitats also isolates frog populations, making it harder for them to interact and maintain genetic diversity.
Species Conservation Challenges
Conserving frog species involves multiple challenges. One major challenge is the lack of awareness and priority given to amphibians compared to other wildlife.

Moreover, action plans for conservation require significant resources, including funding and technical expertise, which are often limited. Another hurdle is dealing with the cumulative impact of different threats such as climate change, habitat loss, disease, and pollution. All these factors can simultaneously affect frog populations, making conservation efforts more complex.
Biotic and Abiotic Factors
Frogs face challenges from both biotic and abiotic factors. Biotic factors include interactions with other living organisms like predators, competitors, and parasites. Abiotic factors are non-living components such as temperature, humidity, and light.

A well-balanced ecosystem ensures the proper function and support for the frog population. Disturbances in either sphere can have ripple effects. For instance, a drop in prey availability (a biotic factor) or a drastic change in temperature (an abiotic factor) can severely affect frog survival.
Human Impact on Wildlife
Human activities have a profound impact on wildlife, including frog populations. Some key influencing factors include pollution, deforestation, climate modification, and hunting.

Contaminants like pesticides and industrial waste can seep into water bodies, poisoning frogs and their offspring. Urbanization leads to habitat destruction, while agricultural practices often involve the use of harmful chemicals. Addressing human impact involves creating sustainable practices and enforcing regulations to protect frog habitats and other wildlife.

Most popular questions from this chapter

Explain how the increase in human population and resource use causes increased extinction rates by altering ecosystems. a. Human population growth leads to unsustainable resource use, habitat destruction, and the unsustainable fishing and hunting of wild animal populations. All these incidences results in a slow evolutionary rate of formation of new species. b. Human population growth leads to unsustainable resource use, habitat destruction, and the unsustainable fishing and hunting of wild animal populations. Climate change also occurs due to excessive use of fossil fuels. c. Human population growth leads to unsustainable resource use, habitat destruction, and unsustainable fishing and hunting of wild animal populations. Excessive use of fossil fuels is leading to reduced populations of fish species. d. Human population growth leads to unsustainable resource use, habitat destruction, and unsustainable fishing and hunting of wild animal populations. Larger human populations are also leading to decreased value of products obtained from species.

Which of the following activities will result in major habitat loss? a. picking wild flowers in a meadow b. cutting a tree in one鈥檚 backyard c. a farmer switching from wheat to soy crop d. building a dam that will flood a large plain

Backpackers returning from a long trip abroad are stopped by customs and asked whether they brought back plants, flowers or fruit from their trip location. Their fruit bought at a local market is confiscated. Why was the fruit confiscated? a. The hikers are supposed to pay duty on imported fruit. b. The fruit can be processed to produce illicit drugs. c. The fruit seed could be planted and could eliminate all local species. d. The fruit may introduce new exotic pests that threaten local plants.

Findings from layers dating to the Cambrian geological period show an appearance of many new organisms in addition to older forms of life. The Cambrian explosion corresponds to a time where _____. a. New species radiated from existing species. b. New species appeared due to spontaneous mutations. c. Ancient species were replaced by newly evolved species. d. A massive die-out freed ecosystems for new species.
