Science Quiz - Living Things

A decomposer is an organism that breaks down dead organic matter, such as dead plants and animals, into simpler substances. They play a crucial role in the ecosystem by recycling nutrients back into the environment. Decomposers release enzymes that break down the complex molecules in dead matter, allowing them to absorb the nutrients for their own growth and releasing simpler substances that can be used by other organisms. Therefore, the correct answer is "make dead things rot."

In a food web, a producer is an organism that produces its own food through photosynthesis or chemosynthesis. Producers are always at the start of a food web because they are the primary source of energy for other organisms in the ecosystem. They convert sunlight or inorganic compounds into organic matter, which is then consumed by herbivores and subsequently by carnivores and other higher-level consumers. Therefore, it is true that a producer is always at the start of a food web.

A food web is made up of food chains because it represents the interconnectedness of multiple food chains within an ecosystem. It shows how different organisms are linked through their feeding relationships, with each organism being a part of multiple food chains. This concept helps to illustrate the complex interactions and energy flow between different species in an ecosystem.

A weed is a plant that grows where it is not wanted.

The correct answer includes four ways to capture bugs: pooters, sweep nets, pitfall traps, and beating a tree. These methods are commonly used in entomology to collect insects for study or observation. Pooters are small devices used to suck up insects, sweep nets are used to catch flying insects, pitfall traps are containers buried in the ground to trap crawling insects, and beating a tree involves shaking a tree to dislodge insects. These methods provide different approaches to capture bugs depending on their behavior and habitat.

The question is asking for the term that refers to the place where a living thing lives. The correct answer is "habitat." This term is used to describe the specific environment or location where an organism naturally lives and obtains its resources. It includes factors such as climate, food availability, and physical features of the environment. The term "adaptations" mentioned in the question is unrelated to the definition being asked for and refers to the traits or characteristics that enable an organism to survive and reproduce in its habitat.

The first question asks for the term used to describe a living thing that makes its own food, which is a producer. The second question asks for the term used to describe a living thing that eats just meat or animals, which is a carnivore. The third question asks for the term used to describe a living thing that eats both plants and animals, which is an omnivore. The fourth question asks for the term used to describe a person who never eats meat, which is a vegetarian.
