In a pond, the primary producer is a green algae, the primary consumer is the crustacean, the secondary consumer is the bluegill fish, and the tertiary consumer is the small mouth bass. what changes can be expected in the pond if the crustaceans are killed with pesticides?
a. the small mouth bass population will increase.
b. the crustacean population will eat something else.
c. the green algae population will probably increase.
d. the bluegill population will probably increase.
the sun is the primary source of energy for earth's climate system is the first of seven essential principles of climate sciences. principle 1 sets the stage for understanding earth's climate system and energy balance. the sun warms the planet, drives the hydrologic cycle, and makes life on earth possible.
open ocean of any depth, where animals swim or float freely, is called: pelagic zone.
open ocean of any depth is called pelagic zone or open ocean zone. this zone can be assumed as water column or cylinder that goes from the bottom of the sea to almost surface.the mean depth of any pelagic zone is almost 3.68 to 11 kilometers.
in this region, the temperature and pressure may vary as we go from top to bottom of the zone of any depth however, the zone is called same pelagic zone.
this is because while going from top to bottom of ocean the light penetration becomes less, this causes a drop in the temperature of ocean. therefore, the atmosphere of ocean can further be subdivided into different zones based on the factors like pressure and temperature.
hope it !
animal cells have many distinct characteristics when compared to plant cells, including their varied shapes, their many types of organelles, their centrioles, cilia and lysosomes, and their cell-to-cell junctions. animal cells also lack chloroplasts and cell walls, which are found in plant cells.
