Become better prepared for the TASC Science test by studying this Biodiversity & Humans chapter. The particular focuses of these lessons include the following:
- Biodiversity and its relationship to the stability of the ecosystem
- The difference between background extinction and mass extinction
- Different applications of environmental sustainability
- Human behavioral threats to environmental sustainability
- Sustainable development within environmental limits
- Definition and complexities of sustainable consumption
- Overpopulation vs. overconsumption
Our professional instructors take you through these topics using short and highly effective educational videos and informative text discussions. Once you've completed a lesson you can quickly gauge your comprehension and comfort with the material by taking a practice quiz.
Objectives of the TASC Science: Biodiversity & Humans Chapter
The TASC Science exam and its items are designed to determine if your subject knowledge aligns with what's expected of typical high school seniors. The exam includes content from three main subareas of science, including an Earth and space sciences content area that targets Earth and human activity and a life sciences area that addresses ecosystems. If you're taking the computer-based version of the exam there will be 48 multiple-choice questions and a technology-enhanced question, and the paper version has 49 multiple-choice questions. Each format also includes one constructed-response item.
1. What is Biodiversity? - Definition and Relation to Ecosystem Stability
Imagine making a list of all of the species you have ever heard of; it would be an enormous list! There are many different species on this planet. This lesson will explore the diversity of species, as well as the different types of diversity and how diversity of life is essential for maintaining healthy ecosystems.
2. What Is Extinction? - Defining Background and Mass Extinction
In this lesson you'll discover what the term 'extinction' means as well as learn the two different types of extinction: mass extinction and background extinction. You will also discover how humans contribute to extinction events.
3. Environmental Sustainability: Definition and Application
Environmental sustainability allows for the needs of man to be met without jeopardizing the ability of future generations to meet their needs. Learn applications of environmental sustainability, including sustainable agriculture, forestry and energy.
4. Human Behaviors that Threaten Environmental Sustainability
The environment has a remarkable ability to sustain itself. However, human behaviors disrupt the natural environment and threaten environmental sustainability. Learn how population growth, depletion of resources, and pollution threaten nature.
5. Sustainable Development within Environmental Limits
Sustainable development is a way of meeting the needs of both present and future generations. Learn how sustainable development must work within the environmental limits so future generations can benefit from the rich resources of the environment.
6. Sustainable Consumption: Definition and Complexities
Sustainable consumption is the use of products and services that have a minimal impact on the environment so future generations can meet their needs. Learn about the benefits and the complexities that are associated with sustainable consumption.
7. Overpopulation vs. Overconsumption
How many people can the Earth support? In this lesson, we will explore population growth and some of the concerns associated with this growth, including overpopulation and overconsumption.
