1.each of several hierarchical levels in an ecosystem, comprising organisms that share the same function in the food chain and the same nutritional relationship to the primary sources of energy.
A scavenger is an organism that mostly consumes decaying biomass, such as meat or rotting plant material. Many scavengers are a type of carnivore, which is an organism that eats meat. While most carnivores hunt and kill their prey, scavengers usually consume animals that have either died of natural causes or been killed by another carnivore.
Scavengers are a part of the food web, a description of which organisms eat which other organisms in the wild. Organisms in the food web are grouped into trophic, or nutritional, levels. There are three trophic levels. Autotrophs, organisms that produce their own food, are the first trophic level. These include plants and algae. Herbivores, or organisms that consume plants and other autotrophs, are the second trophic level. Scavengers, other carnivores, and omnivores, organisms that consume both plants and animals, are the third trophic level.
Nitrogen is converted from atmospheric nitrogen (N2) into usable forms, such as NO2-, in a process known as fixation. The majority of nitrogen is fixed by bacteria, most of which are symbiotic with plants. Recently fixed ammonia is then converted to biologically useful forms by specialized bacteria.
Answer: Subarachnoid
Explanation:
The space in the meninges below the arachnoid membrane and above the pia mater contains the cerebrospinal fluid. Cerebrospinal fluid is produced by choriod plexus( a cluster of capillaries) from the blood. Blood vessels traveling within the subarachnoid space deliver oxygen and nutrients to the spinal cord.
Answer:
technically its everyone's but isn't at the same time
Explanation:
The UN Convention on the Law of the Seas states the different rights and regulations regarding specific nations’ rights to oceans. For instance, coastal states have jurisdiction over the 12 nautical miles off their coastlines, and 200 nautical miles are reserved for specific states to utilize the oceanic materials, living and nonliving, in their zone. This can include fishing, the mining of minerals but also includes the obligation to protect the ocean and its biodiversity.
Answer:
Thick diameter, Myelinated
Explanation:
A alpha neurons conduct action potentials faster because of their large axon diameter and myelin.
- The large diameter is less resistant to the flow of ions and allows for faster conductivity.
- The myelin sheath is a layer of fat acting as to insulate the axon which helps increase signal conductance.
