What would happen in a food chain if decomposers were removed?
What would happen in a food chain if decomposers were removed?
Tap to reveal answer
If decomposers were removed from a food chain, there would be a break down in the flow of matter and energy. Waste and dead organisms would pile up. Producers would not have enough nutrients because, within the waste and dead organisms, nutrients would not be released back into the ecosystem.

Tap to reveal answer
A decomposer is an organism that feeds on and breaks down dead plant or animal matter, making organic nutrients available to the ecosystem. Often a decomposer is a bacterium, fungus, or invertebrate. Decomposers play a critical role in the flow of energy through an ecosystem. Decomposers make vital nutrients available to an ecosystem’s primary producers—usually plants and algae. A worm, bacterium, or fungi would all be acceptable examples of a decomposer.

How do decomposers assist producers in moving matter in the food chain?
Tap to reveal answer
Decomposers play a vital role in keeping the food chain functioning properly. As decomposers break down the remains of dead organisms and produce waste, nutrients are recycled back into the soil for producers (plants) to absorb through their roots. Without decomposers, there would be a buildup of debris, remained, and a lack of nutrients in the food chain.

Which of the following groups are examples of carnivores?
Which of the following groups are examples of carnivores?
Tap to reveal answer
Animals that hunt and eat other animals are called carnivores. This means they eat only meat. Animals like wolves, tigers, and cheetahs are examples of carnivores. They have specially adapted features to allow them to excel at hunting and eating meat. Strong talons, sharp beaks, sharp teeth, powerful jaw, and night vision are just a few adaptations. They still receive energy from the Sun and producers as they consume other animals in the food chain, but they do not directly eat the producers.

Which answer choice below describes an omnivore and gives an accurate example of one?
Tap to reveal answer
Omnivores are organisms that eat both plant and animal products. Humans are an example of an omnivore because we eat meat like beef, pork, fish, and chicken and eat fruits and vegetables, which are plants or plant by-products. A carnivore only eats animal products (like a cheetah), and herbivores only eat plants and plant by-products (like a rabbit).

Tap to reveal answer
In this scenario, the plants with the most growth would be the plants in tray A. The plants in tray A received not only water (which plants must have to survive) but also sunlight. Plants need sunlight for the process of photosynthesis. If plants do not have access to air and sunlight, they cannot make their food and survive. The plants in tray B were deprived of sunlight, so they will not have as much growth as tray A.

Plants and trees can grow in a wide variety of environments. Whether they grow in the desert or the rainforest, they all have one thing in common, air and water are necessary for life and growth. Depending on the plant's adaptations, the amount of water needed to survive varies. Some plants, like those in the desert, need very little water to grow. Plants primarily get the materials for growth from the air and water. Sunlight provides the energy that is required to create food through photosynthesis. We often see plants in soil, but it isn't necessary for growth.
Hydroponics is a system of growing plants without soil. Nutrients are added to water and delivered directly through a plant's roots. Plants do not gain anything from the earth itself; they absorb nutrients from within the soil. If those nutrients are added to the water, and the plant is in the open air, then the soil is not needed. Plants take in carbon dioxide from the air and convert it into glucose through the process of photosynthesis, which is powered by sunlight. Hydroponics come in numerous forms: the plants can be hung vertically, and the roots are sprayed, or roots may be submerged in water through a series of tubs, containers, or even coconut husks!

Why is water important to a plant's survival?
Tap to reveal answer
Water is one of just a few things plants need to survive. Water supports the transportation of nutrients, from the soil up into the structures of the plant, is used in the process of photosynthesis, helps keep plants standing stiff and upright and not wilted or droopy, and water helps keep plants cool as it evaporates from the leaves. If plants do not have access to water, they will not absorb the nutrients needed to grow.

Tap to reveal answer
Plants (producers) are at the beginning of every food chain that involves the Sun. All energy comes from the Sun, and plants are the ones who make food with that energy through photosynthesis. Plants get their energy from the Sun and water. Without water transporting nutrients to the plants, they would not grow and survive. Water also helps cool plants as they evaporate water through transpiration.
