The 6 terrestrial ecosystems are tundra, taiga, temperate deciduous forest, tropical rain forest, grassland, and desert, these are distinguished from aquatic ecosystem by the limited supply of water. The two types of aquatic ecosystems are marine and freshwater.

Terrestrial productivity is more effective in the wet tropical climates as the net primary productivity decreases between equatorial and polar regions due to less sunlight and therefore there is a temperature decrease. Global productivity is limited by factors of water and sun, as most ecosystems rely on photosynthesis and water. Marine productivity tends to be higher, as rivers and water carry more nutrients and deposit them in other ecosystems. The most productive regions are areas such as wetlands and estuaries. i hope this helps!

Approximately 72% of Earth’s surface is covered by aquatic ecosystems, but they only account for supporting about 1/3 of the biosphere’s primary producers. This compares to terrestrial ecosystems which cover 28% of Earth’s surface yet account for the remaining 2/3 of the biosphere’s primary producers. Taken together this means terrestrial ecosystems are 5-6 times more productive than aquatic ecosystems per unit area.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this and an i get brainlsiest

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
