1.

What is the source of energy for producers?

Answer: The Sun
Explanation:
Producers, also known as autotrophs, are organisms that can produce their own food through photosynthesis. The process of photosynthesis requires energy, which is obtained from the Sun. The Sun serves as the ultimate source of energy for producers, as it provides the light energy necessary for photosynthesis to occur. Therefore, the correct answer is "The Sun."
2.

What kind of organism comes last in every food chain?

Answer: Decomposers
Explanation:
Decomposers come last in every food chain because they break down dead organic matter and recycle nutrients back into the ecosystem. They play a crucial role in the food chain by breaking down the remains of plants and animals, returning essential nutrients to the soil or water. This process allows for the continued growth of producers, which are then consumed by consumers, and the cycle repeats. Decomposers are essential for maintaining the balance and sustainability of ecosystems.
3.

Transpiration is a process in plants that is responsible for:

Answer: Releasing the water
Explanation:
Transpiration is the process in plants where water is released from the leaves through small openings called stomata. This water loss occurs due to the evaporation of water from the leaf surface. Transpiration helps in maintaining the water balance in plants and plays a crucial role in the movement of water from the roots to the leaves. It also aids in cooling the plant and facilitating the uptake of nutrients. Therefore, the correct answer is "Releasing the water".
4.

When a plant performs the process of photosynthesis, what substance is produced?

Answer: Oxygen and Glucose
Explanation:
During the process of photosynthesis, plants convert sunlight, water, and carbon dioxide into glucose (a type of sugar) and oxygen. Oxygen is produced as a byproduct of photosynthesis and is released into the atmosphere. This oxygen is essential for the survival of many organisms, including humans, as it is needed for respiration. Therefore, the correct answer is oxygen and glucose.
5.

Plants are also called:

Answer: Producers
Explanation:
Plants are called producers because they have the ability to produce their own food through the process of photosynthesis. They convert sunlight, water, and carbon dioxide into glucose and oxygen, which is a fundamental process for sustaining life on Earth. Unlike consumers, which obtain energy by consuming other organisms, and decomposers, which break down dead organic matter, plants are unique in their ability to synthesize their own food, making them the primary source of energy in most ecosystems.
6.

A food web is:

Answer: Inter lapping food chains
Explanation:
 A food web refers to the interconnected feeding relationships between different organisms in an ecosystem. It consists of multiple food chains that overlap and interact with each other. Each food chain represents a series of organisms where one organism is eaten by another, forming a relatively linear pathway of energy transfer. The concept of interlapping food chains emphasizes the complex and interconnected nature of these relationships within an ecosystem.
7.

The correct order of the following sequence ( rabbit, fox, carrots, fungi) in a food chain would be:

Answer: Carrot, rabbit, fox, fungi
Explanation:
 In a food chain, the organisms are arranged in the order of how organisms derive energy. Carrots are a producer; they are at the bottom of the food chain and are eaten by herbivores.. Rabbits are herbivores and eat carrots, so they come after carrots in the sequence. Foxes are carnivores and eat rabbits, so they come after rabbits. Fungi are decomposers and break down dead organisms, so they come at the end of the food chain.
8.

Nutrients are returned to the ecosystem by:

Answer: Decomposers
Explanation:
Decomposers play a vital role in returning nutrients to the ecosystem. They break down dead organisms and organic waste, releasing nutrients back into the environment. Through the process of decomposition, decomposers such as bacteria and fungi break down complex organic matter into simpler forms, which can then be utilized by producers (plants) to perform photosynthesis and produce food. This nutrient cycling is crucial for maintaining the balance and sustainability of the ecosystem.
9.

A community of organisms living together is called an _______.

Answer: Ecosystem
Explanation:
An ecosystem refers to a community of organisms that live together in a specific area and interact with each other and their environment. It includes both living organisms, such as plants, animals, and microorganisms, as well as the non-living components, such as soil, water, and air. The interactions within an ecosystem are complex and involve processes like energy flow, nutrient cycling, and ecological relationships. By studying ecosystems, scientists gain insights into the interdependence of organisms and their environment, helping to understand the functioning and balance of natural systems.
10.

What is the flow of energy between organisms called?

Answer: Food web
Explanation:
A food web describes the complex and interconnected relationships through which energy flows in an ecosystem, from producers like plants and algae that create their own food via photosynthesis, to various levels of consumers (herbivores, carnivores) that rely on each other for energy, and finally to decomposers that break down dead organisms. This network of energy transfers, more detailed than a linear food chain, showcases how each species is linked and emphasizes the balance necessary for ecological stability.
