Answer:
Bio gas
Explanation:
Bio gas is gotten from the anaerobic breaking down of biomass especially animal waste.
PROS:
A. it is renewable: biogas is renewable and has an endless supply of material since animals are the main source when compared to fossil fuels.
B. It doesn't involve a rigorous mining exersice to get to like fossil fuels and it is in accessible abundance.
CON:
A. A lot of waste is needed for the product of biogas and the final waste (sludge) from the production process can be a huge problem to dispose off.
B. Some of the gases liberated in the manufacturing process are greenhouse gas, especially methane. These gases if let out, will contribute immensly to global warming.
46 points How do erosion and deposition work together to create a moraine?
Waves cause erosion along coastlines and deposit sand away from the shore.
Surface water in rivers causes erosion, carrying sediment that gets deposited near an ocean.

What might be some possible issues of increasing heat waves?
Answer:
Extreme heat can cause cramps, swelling, and fainting. Heat waves kill more Americans than other natural disasters such as floods, lightning, tornadoes, and hurricanes. Heat exhaustion is a relatively common reaction to severe heat and can include symptoms such as dizziness, headache and fainting. But when sustained heat waves hit a region, the other health ramifications can be serious, including sunstroke and even major organ damage due to heat. Heat stress, or when too much heat, is absorbed by the body can cause extreme exhaustion but can also mess with our thinking, making things like everyday tasks and simple math a little harder to do.

How much energy do consumers obtain when they eat
Answer: it’s 10%
Explanation: Primary consumers only obtain a fraction of the total solar energy—about 10%—captured by the producers they eat. The other 90% is used by the producer for growth, reproduction, and survival, or it is lost as heat. You can probably see where this is going. Primary consumers are eaten by secondary consumers.

What is carrying capacity?
the maximum number of organisms that can
live in a population
the ability of the environment to provide
resources for a growing population
the maximum number of organisms an
environment can support for a long time
the maximum number of species that can
live in an ecosystem.
Answer:
The maximum number of organisms an environment can support for a long time
The maximum number of organisms an environment can support for a long time.
What is carrying capacity?Carrying capacity refers to the maximum population size of a particular species that a given ecosystem or environment can sustain indefinitely. It represents the balance between the resources available in the environment and the needs of the population. Once the population reaches the carrying capacity, the available resources may become limited, leading to increased competition for food, water, shelter, and other necessities.
This can result in population stabilization or fluctuations as the ecosystem tries to maintain equilibrium. Understanding the carrying capacity of an environment is important for managing and conserving populations and maintaining the long-term sustainability of ecosystems.
