Answer:
Cnidarians.
Explanation:
Cnidarians are known as the marine invertebrates, and also called as Coelenterata, they belong to phylum Cnidaria. Cnidarians include sea fans, sea pens, corals, hydra, jellyfish, and sea anemones. They belong to four classes: Anthozoa, Cubozoa, Hydrozoa, Scyphozoa.
Cnidarian captures its prey with the help of nematocysts which are thread-like tubes, coiled, and sticky. Nematocysts contain toxin by the release of this toxin corals hunt their prey, and even while they are stuck to the ocean floor.
The Lithosphere contains all of the cold, hard, solid rock of the planet's crust, the hot semi-solid rock below the crust, the hot liquid rock near the center of the planet, and the solid iron core. The biosphere is the sphere that contains all of the Earth's living organisms. The organisms and crust interact through events between spheres, such as natural events like floods, shifts in the Earth's crust. Some event as such could create soil erosion resulting in decreased vegetation and increase death of organisms. <span>

Answer:
The correct answer is - option 1. 930 kilocalories.
Explanation:
In every ecosystem, the energy is passed from one form to another and there is a lot of loss of the energy as heat in the cellular process. There is a transfer of only 10% of each level of the trophic level.
Algae is the producers in this aquatic ecosystem so the primary consumer will get 10% of the energy that is present in plant tissue (93000kcal) which will be 9300 Kcal and second producers will get 10% of this will be 930Kcal.
Thus, the correct answer is option 1. 930 kilocalories.
