Which biome covers the largest part of earth's surface?grassland
polar
marine
tropical rain forest

Answers

The oceans cover the earth's surface by approximately three-fourth or seventy five percent. It is the oldest and the largest biome. Thus, the marine biome is the largest biome which covers the earth's surface. This biome also is the common link among the other biomes in Earth.

Final answer:

The marine biome covers the largest part of Earth's surface, constituting about 71% of it. This biome is characterized by its saline water environment, diverse marine life, and significant role in maintaining the balance of Earth's ecosystem.

Explanation:

The biome that covers the largest part of Earth's surface is the marine biome, and it outflanks other biomes by a significant margin. Biomes are large biological environments characterized by certain types of flora and fauna, weather patterns, and other ecological traits. In our case, the various types of marine biomes altogether constitute approximately 71% of the Earth's surface, significantly outpacing the other biomes.

Characterized by its saline water-related features, this biome includes oceans, seas, reefs, and other bodies of saltwater. Marine life is incredibly diverse, encompassing extensive ranges of animal, plant, and microbial life forms. Unlike terrestrial biomes, such as the grassland, polar, and tropical rainforest, whose habitats are dominated by land-based life, the marine biome is characterized mainly by aquatic life.

It's important to note the significant role that the marine biome plays in the Earth's ecosystem. Its vast bodies of water regulate global weather patterns and provide a home for a massive quantity of the Earth's biodiversity.

A symbiotic relationship in which one species benefits and the other is harmed but not immediately killed is known as?

Answers

Answer:

Parasitism.

Explanation:

A biological interaction explains the different relationship between the organism and their interaction in the environment. The different biological interaction are mutualism, ammensalism and parasitism.

Parasitism may be defined as the type of symbiotic relationship in which the organisms are associated with each other. The one species gets benefit from the other organism while the other organism is harmed but they are ot killed directly or immediately. This is a type of negative interaction.

Thus, the answer is parasitism.

It's called parasitism.

When particles move out of a cell through facilitated diffusion, the cell A. first gains and then uses energy
B. does not use energy
C. uses energy
D. uses energy

Answers

When particles move out of a cell through facilitated diffusion, the correct answer B. is the cell does not use energy.

Facilitated diffusion is diffusion mediated via way of means of delivery proteins. The materials flow down the attention gradient from better to decrease attention so it does now no longer require energy.

What is Facilitated diffusion?

Facilitated diffusion (additionally referred to as facilitated shipping or passive-mediated shipping) is the system of spontaneous passive absorption (in place of lively shipping) of molecules or ions throughout an organic membrane through precise transmembrane essential proteins. Facilitated diffusion is an instance of passive shipping. Materials pass into or out of cells thru channel proteins. The debris pass from regions of excessive attention to regions of low attention.

Thus it is clear that when particles move out of a cell through facilitated diffusion, the cell does not use energy.
