What name is given to the region where photosynthesis can occur?
The photic zone, euphotic zone, epipelagic zone, or sunlight zone is the uppermost layer of a body of water that receives sunlight, allowing phytoplankton to perform photosynthesis. It undergoes a series of physical, chemical, and biological processes that supply nutrients into the upper water column.
What level of ecology is concerned with groups of individual of different species?
Community ecology focuses on the processes driving interactions between differing species and their overall consequences.
What is the name given to the seafloor?
The seabed (also known as the seafloor, sea floor, ocean floor, and ocean bottom) is the bottom of the ocean. All floors of the ocean are known as ‘seabeds’.
What are open oceans called?
The pelagic zone, also known as the open ocean, is the area of the ocean outside of coastal areas.
What level of ecology is concerned with energy flow and nutrient cycling?
Ecosystem ecology is an inherently interdisciplinary field of study. An individual ecosystem is composed of populations of organisms, interacting within communities, and contributing to the cycling of nutrients and the flow of energy. The ecosystem is the principal unit of study in ecosystem ecology.
Which of the biomes is maintained by fire?
Grasslands. A grassland is a “fire-maintained” ecosystem, thus frequent fires are good. It returns nutrients to the soil, accommodating in productivity.
Why are most food chains limited to three to five trophic levels?
Why are most food chains limited to three to five trophic levels? There is insufficient energy to support more trophic levels.
Is deep sea water salty?
Deep ocean water (DOW) is the name for cold, salty water found deep below the surface of Earth’s oceans. Deep ocean water has a very uniform temperature, around 0-3 °C, and a salinity of about 3.5% or, as oceanographers state, 35 ppt (parts per thousand).
