How populations grow when they have unlimited resources (and how resource limits change that pattern).
An ecosystem is a community of living organisms and their physical environment interacting as a system.
Learn about age structure diagrams and their significance in understanding human population dynamics on Khan Academy.
For instance, a community may have sharp edges or may blend gradually into the neighboring community. Also, different populations may occupy different areas inside the community's boundaries. In this article, we'll mostly focus on community structure as defined by species composition.
Exponential growth presumes infinite resources, resulting in unrestrained population expansion. Conversely, logistic growth considers resource limitations and a carrying capacity (K) - the maximum sustainable population.
Course: Middle school biology > Unit 6. Lesson 1: Ecosystem dynamics. Ecosystem dynamics: Clark’s nutcrackers and the white bark pine. Ecosystem dynamics. Understand: ecosystem dynamics. Apply: ecosystem dynamics.
Evidence for evolution: anatomy, molecular biology, biogeography, fossils, & direct observation.
Rabbit populations grow exponentially when not limited by resources, space, or predators. Exponential growth has time in the exponent, causing a rapid increase in population size. In real-world situations, logistic growth is more accurate due to environmental constraints.
