While savannas and temperate grasslands are both types of
grasslands and share many characteristics, they also have
some differences. Compare them below by writing each
characteristic in the correct location. You will use each only
once.
• home to many types of grazers
• experience all seasons of weather
• home to bison
• home to the African elephant
• example: tallgrass prairies of North America
• example: Serengeti in Tanzania
• also known as tropical grasslands
• few trees due to little rainfall
1)
(Savannas)
(Both Types of
Grasslands)
(Temperate
Grasslands)
Answer:
S - Savannas are typically found in tropical or subtropical regions.
S - Savannas tend to have more trees and shrubs.
S - Savanna's climate is drier than that of a grassland.
G - Grasslands are found in temperature regions.
G - Temperature Grasslands are mainly devoid of trees, receive less rainfall than Savannas & endure broader temperature extremes.
G - Grasslands make up 25 percent of the Earth's land surface and dominate in regions with limited rainfall, which prevents forest growth. This results from nearby mountain ranges that cause rain shadows over adjacent open-range lands.
B - Both represent the world's richest and most diverse ecosystems. They both provide a home for a quarter of the world's population and a habitat for thousands of plants and animals.
B - Many species gather in vast numbers, graze on the varied grasses, and can be found nowhere else on Earth. The coexistence between wildlife and grasses is key to healthy ecosystems. Animal migrations regenerate the landscapes, by controlling pests, dispersing seeds, and trampling invasive species. Through this partnership, grasslands and savannahs generate vital benefits for both people and nature.
B - Ecosystems such as these two in specific are essential for climate mitigation – they store carbon, locking it deep in the soil and extensive root systems. They are the source of or support many of the world’s biggest rivers and wetlands, ensure food security, support livelihoods, and are embedded in the cultural identity of millions of people.
(Also, A savanna or savannah is a mixed woodland-grassland<---similarity)
Explanation: Just research. I decided to state 3 characteristics for both The Savanna and The Grasslands, and then 3 for "B" (both).

write a paragraph describing which type of composting method you think would work best for your home. (dream home, apartment, or the current house you are living in)
Answer:
Worm Farm Composting for many, is the most common and preferred choice of composting because of their capabilities to grow worms, produce compost and compost tea and keep rats out of your compost. The worms produce castings concentrated with nutrients lower in nitrogen compared to other composting methods. Worm composting is using worms to recycle food scraps and other organic material into a valuable soil amendment called vermicompost, or worm compost. Worms eat food scraps, which become compost as they pass through the worm's body. Compost exits the worm through its' tail end. This compost can then be used to grow plants. To understand why vermicompost is good for plants, remember that the worms are eating nutrient-rich fruit and vegetable scraps, and turning them into nutrient-rich compost.
Explanation:
Worm composting is good for planting and things like that in that nature.
Vermiculture composting, using a worm bin indoors, is the ideal method for my limited space, creating odorless compost for my plants.
Considering the current house I am living in, a vermiculture composting method would work best for me. As an urban dweller, space is limited, and vermiculture composting offers a compact and efficient solution. By utilizing a worm bin, I can easily transform kitchen scraps and organic waste into nutrient-rich compost. The process is odorless and can be conveniently managed indoors, making it suitable for year-round composting.
The worms efficiently break down the organic matter, producing vermicompost, a potent fertilizer for my indoor and outdoor plants. This method is low-maintenance, requiring minimal effort and space. Additionally, vermiculture composting aligns with my sustainability goals by reducing waste and creating a closed-loop system within the confines of my home. It offers an eco-friendly and practical approach to composting, perfect for my current living situation.

It has many function I will name at least two of them:It protects the plant from microbes like bacteria and viruses. It makes the cell strong so it wont chnge its shape alot so the plant will stand vertically without any bone or other things. It controls passing molecules like Glucose or amino acid..In torgesans of the cell the cell wall will protect the cell against exploding.I think thats enough.
Answer:
The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.

4.plants grow from the soil
Answer:
2
Explanation:
Energy is transferred between organisms in food webs from producers to consumers.
The energy is used by organisms to carry out complex tasks. The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants.
Answer: between organisms in food webs from producers to consumers.
Explanation:
identify and describe two technologies that have changed the way humans influence the inheritance of desired traits in plants and/or animals.
Mechanical energy can take on many forms, but these different forms can be categorized as either potential energy or energy of motion. The height an object is dropped from has an effect on the amount of energy in the object. Let’s conduct an experiment to see the effect.
