  • The starfish Pisaster amongst the rocky intertidal communities of the American Pacific coast is a significant Predator.

    The starfish Pisaster ochraceus is a keystone species in the rocky marine intertidal communities off the northwest coast of North America. This predatory starfish feeds on the mussel Mytilus californianus and is responsible for maintaining much of the local diversity of species within certain communities.

  • Predation can be considered as Nature’s Way Of Transferring Energy To Higher Trophic Levels

    Predation is an interaction in which one organism, the predator, eats all or part of the body of another organism, the prey. Herbivory is a form of predation in which the prey organism is a plant. Predator and prey populations affect each other's dynamics.

  • In Predation, Parasitism, Commensalism the interacting species stay close together.

    Symbiosis is a general term for interspecific interactions in which two species live together in a long-term, intimate association. In everyday life, we sometimes use the term symbiosis to mean a relationship that benefits both parties.

  • The region of biosphere reserve which is legally protected and where no human activity is allowed is known as Core Zone

    Biosphere reserve consist of three zones, i.e, core, buffer and transition zone. Core zone comprises an undisturbed and legally protected buffer zone surrounds the core area and transitions zone is the outermost area of the biosphere reserve, where active cooperation between reserve management and the local people occur.

  • The hot spots of biodiversity are characterized by High Endemicity And High Threat Of Extinction.

    In most cases, areas which have been published as biodiversity hotspots are characterized by high values of a, i.e. by rich compositions of vascular plant species and high rates of endemism.

  • The most important reason for biodiversity loss in today’s age is Fragmentation And Habitat Loss

    The major cause of the decrease in biodiversity is due to the process by which the animal’s natural habitat is destroyed which results in the change in habitat, this is called habitat destruction or habitat loss.

    Additional information:

    -Biodiversity is the presence of a variety of life on earth.
    -It can be measured on three levels: genetic, species, and ecosystem level.
    -Biodiversity is more towards the tropics while terrestrial biodiversity is present at the equator.
    -When the natural habitat is unable to support the life which exists there, then they will lose themselves or die resulting in a reduction in biodiversity.
    -The main reason for the decrease in biodiversity is overpopulation, global warming, deforestation, and pollution.
    -The major biodiversity reducing factor is habitat destruction.
    -It may also occur due to the change in the environment, the introduction of invasive species, loss of water, minerals, and nutrients from the habitat.
    -The loss of habitat will result in fragmentation of habitat leading to small habitats with few organisms.
    -The exotic species are those which are not found locally and are introduced from another country.
    -Over-exploitation refers to the use of any resource until it is destroyed.

  • The growth in arthropods goes along with Ecdysis And Molting

    In order to cope with this situation, arthropods undergo a process of shedding their exoskeleton and forming a new one periodically throughout their lifetime. This process, shown in Figure below, is called molting, or ecdysis, and is regulated by special hormones that coordinate molting events with stages of growth.

  • The electric current is produced when electron move from one position to another position.

    The mobility of electrons decide the magnitude of electric current and the number of electrons will decide the resistivity.

    The charge of electrons is correlated to electric current.

    The electric current will be produced in the direction of opposite to the flow of electrons.
    The drift current is produced in the circuit in the direction of movement of electrons.
