The statement accurately defines ecosystems as the combination of living and nonliving elements in an environment and their interactions. This definition highlights the interconnectedness and interdependence of organisms and their surroundings. Therefore, the answer is true.

Plants are classified as producers because they are capable of photosynthesis, which is the process of converting sunlight into energy. Through photosynthesis, plants produce their own food in the form of glucose, using carbon dioxide and water. This ability to produce their own food makes plants the primary source of energy in most ecosystems. They provide food and energy for other organisms, such as herbivores, which consume plants. Therefore, the correct answer is "Producers."

In all ecosystems, both living and nonliving things can be found. Ecosystems are composed of a combination of living organisms, such as plants, animals, and microorganisms, as well as nonliving elements like water, air, sunlight, and soil. These components interact and depend on each other for survival and functioning of the ecosystem. Living things rely on nonliving things for resources like food, water, and shelter, while nonliving things are influenced and impacted by the activities of living organisms. Therefore, the presence of both living and nonliving things is a characteristic feature of all ecosystems.

Animals rely on their habitats to meet their basic needs for survival. Habitats provide animals with the necessary resources like food, water, air, and shelter. These resources are essential for animals to find and consume food, drink water, breathe oxygen, and seek protection from predators or harsh weather conditions. Therefore, it is true that animals live in habitats that provide everything they need for survival.

A cement playground is not an ecosystem because it does not contain a community of living organisms interacting with each other and their environment. Ecosystems are characterized by the presence of plants, animals, and microorganisms that depend on each other for survival. In contrast, a cement playground is an artificial, man-made structure that lacks the biodiversity and ecological processes found in natural ecosystems.

Nonliving things refer to objects or entities that do not possess life or biological processes. In this context, soil and sunlight are examples of nonliving things. Soil is a natural resource composed of minerals, organic matter, water, and air, while sunlight is a form of electromagnetic radiation emitted by the sun. Both soil and sunlight do not have life and are therefore considered nonliving. Plants, on the other hand, are living organisms as they possess cellular structures, undergo growth, and exhibit various biological processes. Hence, the correct answer is both a and b, referring to soil and sunlight as nonliving things.

This statement is false because habitats can indeed be changed by humans. Human activities such as deforestation, urbanization, and pollution can significantly alter natural habitats, leading to the displacement or extinction of certain species. Additionally, humans can create artificial habitats such as gardens, parks, and zoos, which are specifically designed and maintained for certain species to thrive. Therefore, it is incorrect to claim that habitats cannot be changed by humans.

Living things in an ecosystem refer to organisms that are alive and can interact with their environment. Sunlight is not a living thing, it is a source of energy for living organisms. Plants and animals, on the other hand, are living things as they have the ability to grow, reproduce, and respond to stimuli. Rocks, however, are not living things as they do not possess these characteristics. Therefore, the correct answer is "both b and c" because both plants and animals are living things in an ecosystem.

Plants make sugar using sunlight because they undergo a process called photosynthesis. During photosynthesis, plants use the energy from sunlight to convert carbon dioxide and water into glucose (sugar) and oxygen. This process takes place in the chloroplasts of plant cells, where chlorophyll pigments capture sunlight and initiate the chemical reactions necessary for sugar production. Therefore, sunlight is essential for plants to synthesize sugar and provide energy for growth and other metabolic processes.
