Answer:
9.) <em>Humpback Whales</em>
10.) <em>Phytoplankton.</em>
11.) <em>Sotronger upwelling winds</em>
Explanation:
9.) A primary consumer feeds on primary producers, of all the options given Humpback Whales, are the only ones meeting the criteria in the options given since they feed with plankton (a primary producer).
10.) Phytoplankton are the base of the Southern Antarctic Ocean trophic chain. In the nutrient-rich upwelling zone waters, they can reach huge blossoms and are far more common than other forms of zooplankton in this zone.
11.) The productivity of this ecosystem is influenced by the seasonal cycle of the upwelling winds, these peak during the months of December and January, carrying more nutrients and allowing trophic networks to work more efficiently and actively allowing for more productivity.
Earth is a large spherical landmass, which is divided into three major layers, known as crust, mantle, and core. The innermost layer of the Earth is the core.
<h3>What is the core?</h3><h3 />
- The core of the Earth is the innermost layer, present beneath the mantle and crust.
- The core is entirely made up of iron and nickel. The core of the Earth is also called NIFE, which symbolizes the elements present in the core, Iron (Fe) and Nickel (Ni).
- Core has a radius of approximately 1220 kilometers and is responsible for the generation of the magnetic field.
- Core also consists of the earliest history of the planet and is extremely hot, such that the temperature is close to the Sun's temperature.
Thus, the correct answer is Option D.

Answer:
Temperature and pressure
Explanation:
mechanical weathering is the disintegration/breakdown of rocks and this mainly caused the agents of mechanical weathering which are ; water , wind and ice, and this agents of mechanical weathering achieve this due the factors Temperature and pressure.
Temperature : The continuous heating and cooling of rock surfaces cause s wear and tear on the rocks leading to mechanical weathering
pressure : Ice water found in cracks of rocks exert pressure on the rocks and this also causes the rocks to disintegrate overtime
