1.
Consumers that eat only plants are called ___________________.
Correct Answer
C. Herbivores
Explanation
Consumers that eat only plants are called herbivores. Herbivores obtain their energy and nutrients by consuming plant material. They do not eat meat or other animal products. Examples of herbivores include cows, deer, and rabbits. Herbivores play a crucial role in ecosystems by helping to control plant populations and cycling nutrients through their waste.
2.
What is the main source of energy for producers and food chains?
Correct Answer
C. Sun
Explanation
The sun is the main source of energy for producers and food chains. Producers, such as plants, use sunlight to undergo photosynthesis and convert it into chemical energy. This energy is then passed on to herbivores, carnivores, and other organisms in the food chain, ultimately providing energy for all living organisms.
3.
A consumer who eats both plants and animals is called a _____________________.
Correct Answer
B. Omnivores
Explanation
An omnivore is a consumer that eats both plants and animals. They have a diverse diet and can obtain nutrients from both sources. Unlike herbivores, which only eat plants, and carnivores, which only eat animals, omnivores have the ability to consume and digest a wide range of food items. They play an important role in the food chain as they help maintain balance by consuming both producers and consumers.
4.
Consumers that eat only meat are ______________.
Correct Answer
A. Carnivores
Explanation
Consumers that eat only meat are carnivores. Carnivores are animals that primarily consume the flesh of other animals. They have adaptations such as sharp teeth and claws to help them catch and kill their prey. Unlike herbivores, which eat only plants, or omnivores, which eat both plants and animals, carnivores rely solely on meat as their source of energy and nutrients. Decomposers, on the other hand, are organisms that break down dead organic matter.
5.
Living things that break down dead organisms and turn the remains into nutrients that are released into the soil are called __________________.
Correct Answer
B. Decomposers
Explanation
Decomposers are living organisms that play a crucial role in breaking down dead organisms and organic matter. They break down the remains into simpler substances and release nutrients back into the soil. This process is essential for recycling nutrients and maintaining the balance of ecosystems. Producers, on the other hand, are organisms that produce their own food through photosynthesis, while herbivores and omnivores are consumers that obtain energy by consuming other organisms. Therefore, the correct answer for this question is "Decomposers".
6.
Consumers can make their own food.
Correct Answer
B. False
Explanation
The statement "Consumers can make their own food" is false. Consumers, who are individuals or households, typically do not produce their own food but instead rely on purchasing food from producers such as farmers or food manufacturers.
7.
Producers can make their own food.
Correct Answer
A. True
Explanation
Producers, such as plants, have the ability to produce their own food through a process called photosynthesis. During photosynthesis, plants use sunlight, water, and carbon dioxide to produce glucose and oxygen. This ability to create their own food is what sets producers apart from consumers, who rely on consuming other organisms for their energy and nutrients. Therefore, it is true that producers can make their own food.
8.
__________________ is passed along at each link in the food chain.
Correct Answer
C. Energy
Explanation
Energy is passed along at each link in the food chain. This is because organisms in the food chain obtain energy by consuming other organisms. The energy from the consumed organism is transferred to the consumer, allowing it to carry out its life processes and activities. This energy transfer continues as organisms at each trophic level in the food chain are consumed by organisms at the next trophic level. Without the transfer of energy, organisms would not be able to survive and sustain their populations.
9.
Which choice lists three consumers that eat only plants?
Correct Answer
D. Deer, grasshopper, cows
Explanation
Deer, grasshopper, and cows are all consumers that eat only plants. Deer are herbivores that primarily feed on vegetation, grasshoppers are also herbivores that consume plant matter, and cows are known for their diet of grass and other plant materials.
10.
Which choice lists three consumers that eat only meat?
Correct Answer
A. Lions, tigers, sharks
Explanation
The correct answer is lions, tigers, sharks. These three animals are known as apex predators and primarily consume meat as their main source of food. They have sharp teeth and strong jaw muscles that are adapted for hunting and consuming meat.
11.
Which choice lists three consumers who eat meat or plants?
Correct Answer
C. Humans, monkeys, bears
Explanation
The correct answer is humans, monkeys, bears. These three animals are known to be omnivores, meaning they eat both meat and plants. They have adapted to have a varied diet and can consume a wide range of food sources.
12.
_________________ is the name of the process plants use to make their own food.
Correct Answer
D. pHotosynthesis
Explanation
Photosynthesis is the correct answer because it is the process by which plants convert sunlight, water, and carbon dioxide into glucose (sugar) and oxygen. This process allows plants to produce their own food and is essential for their growth and survival. Cooking, sugar, and fast food are not related to the process of plants making their own food through photosynthesis.
13.
Which choice lists two examples of living things that break down dead organisms?
Correct Answer
C. Bacteria and fungi
Explanation
Bacteria and fungi are examples of living things that break down dead organisms. Bacteria play a crucial role in the process of decomposition by breaking down organic matter into simpler compounds, while fungi, such as mushrooms, decompose dead plants and animals. Both bacteria and fungi are important in the recycling of nutrients and the breakdown of dead organic material, contributing to the overall balance of ecosystems.
14.
What type of organisms have to find their source of energy and cannot make it on their own?
Correct Answer
B. Consumer
Explanation
Consumers are organisms that have to find their source of energy and cannot make it on their own. Unlike producers, such as plants, consumers cannot perform photosynthesis to produce their own food. Instead, they rely on consuming other organisms or organic matter to obtain the energy they need to survive. Consumers are typically classified into different categories based on their feeding habits, such as herbivores, carnivores, and omnivores.
15.
I am a __________________.
Correct Answer
B. Omnivore
Explanation
An omnivore is an organism that consumes both plants and animals as part of its diet. This means that they have the ability to obtain nutrients from a variety of sources, including both plant-based and animal-based foods. Unlike herbivores, which only eat plants, and carnivores, which only eat animals, omnivores have the flexibility to adapt their diet based on the availability of different food sources. This adaptability allows them to survive in a wide range of environments and ensures that they can obtain the necessary nutrients for their growth and survival.
