Population Patterns

Will human population growth always be exponential, or will we find a limiting factor we can't avoid? Young scientists learn about both exponential and logistic growth models in various animal populations. They use case studies to...

A complete study of population ecology is covered by this worksheet. Biology or ecology learners answer questions and interpret population graphs. This can be used as the intended guided notes worksheet or assigned as homework.

A lot of learning is packed into these 23 questions about ecosystems. Advanced biology classes apply their knowledge of communities, productivity, biogeochemical cycles, and human impact on the environment by writing short answers for...

How do we predict future population growth? Young researchers investigate various factors affecting the size of our population. As they calculate and interpret graphs to determine factors that could potentially affect increases and...

The total world population is predicted to pass 8 billion by 2025, which is less than 10 years from now. The video focuses on human population growth and the impact it has had and is having on our planet and other populations. It...

With a human population of 7.6 billion and counting, how do we tackle the population problem? Examine the data using a video from an extensive science playlist. The resource explains why the human population began to increase rapidly,...

While 80 percent of people with West Nile Virus show no symptoms, in severe cases, it causes death by infecting the membranes around the spinal cord and brain. The video starts by making population ecology relevant. It includes density...

Along came a spider, who sat down beside her. She screamed, but RJ wouldn't smash it because spiders are a limiting factor for other insects in an ecosystem. In this video, other common limiting factors for populations are listed....

The carrying capacity of an environment varies based on the organisms that live there. Using a virtual lab simulation, scholars test two protists living in their own environments and a third environment where both protists live. They...

Living and non-living things are both a part of an ecosystem. A video begins with ecosystem interactions using biotic and abiotic factors. It also covers food webs, limiting factors, and logistic growth. As a real-world connection, it...
