Ecosystem dynamics
Review your understanding of ecosystem dynamics in this free article aligned to NGSS standards.
Key points:
- Ecosystems are dynamic. This means that the characteristics of ecosystems and their populations vary over time.
- Ecosystems often experience disruptions, or changes. These changes can happen in either living or nonliving parts of an ecosystem. Any change in an ecosystem can affect the populations that live there.
- Some changes make it less likely that organisms in a population will survive and reproduce. These types of changes cause populations to get smaller.
- Other changes make it more likely that organisms in a population will survive and reproduce. These types of changes cause populations to get bigger.
- Interactions that happen in an ecosystem are like a web. So, a change in any one part of an ecosystem can lead to changes in many of the ecosystem’s populations.

- (Edit)"In practice, it is impossible to pinpoint the moment when this happened. But in theory, at some trace, two junglefowl bred along with offspring was genetically different enough from the species of its parents classified as chicken. This chicken would have developed within a junglefowl egg and only produced the very first chicken’s egg on reaching maturity. Looking at it this way, the chicken came first."(32 votes)
- what does disruptions mean(7 votes)
- Something that prevents something from occurring. E.g. if a trench is formed between a population, the populations on opposite sides are not able to reproduce/interact with each other.(13 votes)

- Not sure if I'm correct but I'm pretty sure the color was called orange because it resembled the color of the fruit orange.(6 votes)
- This isn't really a question or a tip, but the unfortunate rule of life is that something that comes into this world must die. Except the immortal jellyfish, those are weird animals that are basically immortal.(8 votes)

- An area of forest burned by a fire. The changes caused by a forest fire affect populations in an ecosystem. Image credit: “Tinder Fire Burn Scar Area" by Coconino National Forest USDA, public domain.(6 votes)
