1. In marine ecology, the term "limiting resources" refers to the availability of essential elements or factors that can restrict the growth, reproduction, or distribution of marine organisms. These resources are in short supply and can limit the population size or distribution of species in a particular ecosystem. Examples of limiting resources in marine ecosystems include nutrients (such as nitrogen, phosphorus, and silica), light, oxygen, and space. For instance, in areas with low nutrient levels, the growth of phytoplankton, which forms the base of the marine food web, may be limited, leading to lower productivity and biodiversity in those regions.2. The concept of carrying capacity in marine ecology refers to the maximum population size of a species that an environment can sustain indefinitely without degrading the habitat. Carrying capacity is influenced by the availability of resources, such as food, water, and space, as well as factors like predation, disease, and competition. When a marine ecosystem reaches its carrying capacity, the growth rate of the population slows down, and the population size stabilizes. This is because the resources available become insufficient to support further population growth. If the population exceeds the carrying capacity, it can lead to resource depletion, increased competition, and a decline in the population size. Therefore, understanding carrying capacity is crucial for managing marine resources and ensuring the long-term sustainability of marine ecosystems.
