Answer:
secondary succession
Explanation:
In the described scenario we have a destruction of an ecosystem because of natural causes, volcano in this case. All that has left after the volcanic eruption has been barren land. After this has happened life started colonizing the volcanic island again, in a process known as primary succession. In the primary succession it is the organisms that have the lowest of requirements for survival that will inhabit the island. Over time, as they die, they will provide biomass for the ground, thus soil will start to form. Once there's soil formed a process called secondary succession will start. In this process the island will start to be inhabited by some plants and smaller animals. These plants and animals will contribute to further enhancing the living conditions on the island, and the island will gradually be getting larger plants and larger animals, thus a new ecosystem will be formed on the place of the old one.
Answer:
1, 3 and 5 are true.
Explanation:
A smaller planet doesn't have the gravity to hold and atmosphere (with oxygen) or water. A larger earth would hold a thicker atmosphere, which would contain more ammonia and methane.
The correct answer is - east to west.
The trade winds are located between the Equator and the mid-latitudes, or rather in the tropical zone. They are found on both, the North Hemisphere and the South Hemisphere.
In the North Hemisphere, the trade winds are also called northeasterly trades. They move in a roughly east to west direction, beginning from the northern parts of the tropical zone, getting southwards, and then make a turn towards the west.
