Answer:
Aquatic ecosystem has two components -
- Biotic components
2.Abiotic components
temperature and amount of sunlight are the part of abiotic component .
while living things like sponges and planktons are the biotic components of ecosystem.
Explanation:
aquatic components are of two types-
freshwater ecosystem( lakes and ponds, river and streams)
marine ecosystem(ocean ecosysyem, estuaries)
planktons-
planktons are found in limnetic zone, availability of sunlight is much here. planktons are zooplanktons and phytoplanktons are very important link in aquatic ecosystem.
sponges
In marine water, the <em>benthic zone</em> is the area below the<em> pelagic zone.</em> Here temperature decreased because of less light perception. This zone is very nutrient rich so organisms which are present here are- bacteria, fungi, sea anemone, sponges and some fishes.
Answer;
-(2) An atom is mostly empty space.
Experiment
-Rutherford conducted the "gold foil" experiment where he shot alpha particles at a thin sheet of gold. The conclusion that can be drawn from these experiment is that an atom is mostly empty space.
-Rutherford found that a small percentage of the particles were deflected, while a majority passed through the sheet. This caused Rutherford to conclude that the mass of an atom was concentrated at its center, as the tiny, dense nucleus was causing the deflections.
