increase in cloud cover
decrease of methane gas
increase in carbon dioxide
There are different reasons for global warming. According to some scientists, increases in carbon dioxide levels are the cause of global warming.
Due to CO2 and other greenhouse gases effect, there is global warming. This is mostly when CO2 is soaks up by infrared energy, it is said to vibrates and re-emits the infrared energy back in all directions.
Note that almost half of that energy goes out into space, and also an approximate of the same half of it returns to Earth as heat, thereby leading to the 'greenhouse effect. '

Sunflowers are producers. A food web includes sunflowers as both producers and consumers. Sunflowers help the soil's food chain replenish its energy. Only herbivores in the food chain use sunflowers as a source of food and energy.
Sunflowers are producers, placing them at the base of the food chain and at the top of a food web. Numerous insects, particularly tiny omnivores, depend on sunflowers for food, energy, and shade. As an illustration, numerous birds eat the seeds it produces, and caterpillars eat the huge leaves it produces.
The abundant seeds that sunflowers generate can be used in salads, baked into bread, or even made into a smooth nut-free sunflower butter. You'll get a bigger crop of edible plants if you grow a kind that produces seeds.
Therefore, sunflowers are producers.

Hypothesis: An idea or explanation that you then test through study and experimentation; written as an "if...then" statement.
B. dead zones
C. global warming
D. algae blooms
Answer: B. Dead Zones
Explanation:
The term "hypoxia" refers to low or depleted oxygen in a water body. Hypoxia is often associated with the overgrowth of certain species of algae, which can lead to oxygen depletion when they die, sink to the bottom, and decompose & Unable to sustain life, these areas, called dead zones, may cause die-offs of fish, shellfish, corals, and aquatic plants.
