The gases and dust that the volcanic eruption releases changes the climate because most particles erupted shade incoming solar radiation causing the global climate to cool down.
What are the different ways to recover grassland ecosystem after volcanic revolution?The volcanic eruption destroys a grassland ecosystem. They burns the place and the plants. The dusts cover up the leaves and the heat kills the seeds and spores of the plants. The recovery isn’t easy and fast.
As the volcano lava cools and subsides, the new vegetation starts to grow.
The seeds are brought by the wind, birds and other animals that are spread over the landform. The rain provides the necessary water for germination. Volcano supplies the necessary minerals that are very good for plant growth.Thus, most particles erupted shade incoming solar radiation causing the global climate to cool down.

Termites share an endosymbiotic relationship with the protozoan that live in their gut. Which statements are true of this relationship? Check all that apply.
A: The termite benefits from the relationship by receiving food from the protozoan.
B: The protozoan benefits from the relationship by receiving shelter and food from the termite.
C: Protozoan only exist inside termites.
Answer:
Explanation:
The true statements are:
-The termite benefits from the relationship by receiving food from the protozoan
-The protozoan benefits from the relationship by receiving shelter and food from the termite
The second statement is obvious. The protozoan lives in the termite, eating what the termite eats and enjoying the shelter the termite provides. The first statement is also true, but poorly worded. the termite does not actually receive food from the protozoan. The protozoan only helps to digest the food that the termite has already consumed.

Why does social science intersect with marine science?
A. Many poems and novels are written about the ocean.
B. Human behavior causes a lot of issues with the ocean.
C. Social science is another important branch of the sciences.
D. These are very different disciplines that have little connection.
Answer:
it's either b or d I think
Social science intersects with marine science because human behavior causes a lot of issues with the ocean.The correct option is B.
The ocean is a body of salt water that covers approximately 70.8% of the Earth and contains 97% of Earth's water, making Earth an ocean world. The term ocean also refers to any of the large bodies of water into which the world ocean is conventionally divided.Distinct names are used to identify five different areas of the ocean: Pacific , Atlantic, Indian, Southern, and Arctic.
Seawater covers approximately 361,000,000 km² of the planet. The ocean is the primary component of the Earth's hydrosphere, and thus essential to life on Earth. The ocean influences climate and weather patterns, the carbon cycle, and the water cycle by acting as a huge heat reservoir.Pollution of water by human activities makes the marine science intersect with social science.
Thus, option B is correct.

After a forest fire, which type of organisms will begin secondary succession?.
Answer:
herbaceous plants
After a fire, species start to recolonize an area, beginning the secondary succession process. The first species to colonize are usually fast growing herbaceous plants, such as conifers or ferns, which require high levels of light.
Pioneering or early successional species are the kind of organisms that usually start secondary succession after a forest fire.
Thus, these creatures include grasses, herbaceous plants, and tiny shrubs that are small and have a rapid rate of growth. They have evolved to colonize and prosper in open, uncontrolled environments.
Pioneering species have developed systems that enable them to quickly germinate, develop, and reproduce while using the sunshine and nutrients that are accessible.
They support soil stability, moisture retention, and the development of additional plant species through improving environmental conditions. These early-successional species provide the way for the ultimate re-emergence of more mature trees and a complex forest ecosystem when secondary succession develops.
