As in many marine ecosystems, copepods represent a major food source for a variety of neustonic and surface-associated species. [ 1 ] The sea surface microlayer (SML) at the air-sea interface is a distinct, under-studied habitat compared to the subsurface and copepods, important components of ocean food webs, have developed key adaptations to ...
The relationships between primary production and environmental conditions have helped account for variation within ecosystem types, allowing ecologists to demonstrate that energy flows more efficiently through aquatic ecosystems than terrestrial ecosystems due to the various bottom-up and top-down controls in play.

[3] [4]: 5 [2]: 458 The biotic and abiotic components are linked together through nutrient cycles and energy flows. [5] "Ecosystem processes" are the transfers of energy and materials from one pool to another. [2]: 458 Ecosystem processes are known to "take place at a wide range of scales". Therefore, the correct scale of study depends on the ...
While ecosystem management can be used as part of a plan for wilderness conservation, it can also be used in intensively managed ecosystems (e.g., agroecosystems and close to nature forestry). [10] Core principles and common themes of ecosystem management: [7] [13]

[9] Students have put on thousands of plays and musicals based on the book to educate their parents and communities about the importance of saving the rainforest. The Great Kapok Tree received a Charlotte Award from the New York State Reading Association. [10]
Ecosystems may be habitats within biomes that form an integrated whole and a dynamically responsive system having both physical and biological complexes. Ecosystem ecology is the science of determining the fluxes of materials (e.g. carbon, phosphorus) between different pools (e.g., tree biomass, soil organic material).

Ecosystem services are the various benefits that humans derive from healthy ecosystems. These ecosystems, when functioning well, offer such things as provision of food, natural pollination of crops, clean air and water, decomposition of wastes, or flood control. Ecosystem services are grouped into four broad categories of services.
