53K Aquatic ecosystems are composed of a community of living organisms and non-living matter living in (or near) a body of water. Learn about the definition and characteristics of aquatic ecosystems, and discover different types of aquatic ecosystems. Related...
MALE STUDENT: What about … well, you said that the nitrogen cycle is also an important nutrient cycle.And there’s a lot of nitrogen in the atmosphere, so I was wondering: Is there a lot of phosphorus in the atmosphere too? FEMALE PROFESSOR: Good question, George.You’re right to gues...
All living organisms need nitrogen to grow, especially plants. Rhizobia can convert atmospheric nitrogen to ammonia, which is how it promotes plant growth, in a process callednitrogen fixation. One may ask, the atmosphere is composed of 78% nitrogen, so why can’t plants take it d...
McKinsey partner Josh Katz helps us make sense of what it is. Josh Katz: A scientist would tell you that it’s things like air, water, or soil: living organisms. Lucia Rahilly: OK, that’s the “natural.” But what about the “capital”? Well, think ...
obtain from thesoil, this will limit the growth rate for the plant. In nature, the nitrogen, phosphorous and potassium often come from the decay of plants that have died. In the case of nitrogen, the recycling ofnitrogenfrom dead to living plants is often theonlysource of nitrogen in the...
