How does an ecosystem(生态系统) work? What makes the populations of different species the way they are? Why are there so many flies and so few wolves? To find an answer, scientists have built mathematical models of food webs, noting who eats whom and how much each one eats. ...
Food chains and food webs are important ecological concepts that describe the relationships between species in an ecosystem and how energy is transferred between them.The two terms are used interchangeably by many people, but there are a lot of differences between the two.Understanding these co...

Then, to demonstrate how this opens-up a transfer of concepts and results between these domains, we use numerical simulation to show conditions where an ecosystem can acquire, hold and recall distributed information about past environmental conditions – i.e. form a distributed ecological memory. ...
Learn more about this topic: Oceanic Food Webs & Nutrient Productivity from Chapter 15 / Lesson 4 2.8K Oceanic food webs show the dietary interconnections among species. In this lesson, explore how nutrient productivity is achieved through the creation and recycling of nutrients, temperature and...
Where do tadpoles live and how do they affect the ecosystem where they live? What are the genus and species of dragonflies, water boatmen, and caddisfly? What trait does the stick insect, goldfish, kingsnake, and dog all have in common? What type of fertilization does a sea anemone, plan...
I find this question of "What is culture" intimidating because culture is such an expansive concept that it’s fairly difficult to define. Most simply, it’s the way we see and do things. And I honestly think about it in an everyday way as the interrelated web of meanings and activities...
This may sound pretty simple, but it takes millions of years for changes to take place.Biodiversity is also very important to the stability of food webs. Damage to them can mean disaster for an entire ecosystem. The extinction of a single animal species can put huge pressure on the numerous...
What is food ecology? What do the organisms in each trophic level eat? What is the bottom of the ocean food chain? What do secondary consumers eat? What is biomass in a food chain? Herbivores are at what trophic level within an ecosystem? What level consumer is an organism that eats onl...
The energy available in an ecosystem is determined by the amount of energy available to the first trophic level of a food chain. Typically, the sun or other chemicals provide this initial energy. As you move through an ecosystem's food chain, energy is lost as heat when an ...
