What is an example of an organism in the 1st trophic level?
The first trophic level is composed of algae and plants. Organisms on this level are called producers, as they make their own food by using photosynthesis to convert light energy into chemical energy. These organisms are known as autotrophs. Examples include seaweed, trees, and various plants.
What is an example of a trophic level?
Many consumers feed at more than one trophic level. Humans, for example, are primary consumers when they eat plants such as vegetables. They are secondary consumers when they eat cows….Trophic Levels.
| Trophic Level | Where It Gets Food | Example |
|---|---|---|
| 1st Trophic Level: Producer | Makes its own food | Plants make food |
What is a trophic level in your own words?
The trophic level of an organism is the position it occupies in a food web. A food chain is a succession of organisms that eat other organisms and may, in turn, be eaten themselves. The trophic level of an organism is the number of steps it is from the start of the chain.
What is the first trophic level called?
producers
The first and lowest level contains the producers, green plants. The plants or their products are consumed by the second-level organisms—the herbivores, or plant eaters. At the third level, primary carnivores, or meat eaters, eat the herbivores; and at the fourth level, secondary carnivores eat the primary carnivores.
What is the first trophic level of food chain?
Roughly speaking, these levels are divided into producers (first trophic level), consumers (second, third, and fourth trophic levels), and decomposers. Producers, also known as autotrophs, make their own food. They make up the first level of every food chain. Autotrophs are usually plants or one-celled organisms.
Is the sun a trophic level?
There are five main trophic levels within a food chain, each of which differs in its nutritional relationship with the primary energy source. The primary energy source in any ecosystem is the Sun (although there are exceptions in deep sea ecosystems). Primary producers make up the first trophic level.
How many trophic levels are there in Biosphere 2?
Here are the five trophic levels: Level 1: Plants (producers) Level 2: Animals that eat plants or herbivores (primary consumers) Level 3: Animals that eat herbivores (secondary consumers, carnivores) Level 4: Animals that eat carnivores (tertiary consumers, carnivores)
Which is the first trophic level in a food chain Mcq?
Explanation : The first trophic level of the food chain is always occupied by green plants which are termed to be producers. This is because producers absorb sunlight, abiotic factor and fix it into food chain. This energy is transferred to organisms in other trophic levels of the food chain.
Which of the following is the first trophic level in the food chain * A herbivores B carnivores C green plants D All of the above?
Producers belong to the first trophic level. Carnivores belong to the third trophic level. They prepare their own food by photosynthesis.
What trophic level is grasshopper?
primary consumers
Primary producers are the 1st trophic level. Grasshoppers are herbivores that eat grass. Therefore, they are one trophic level higher than grass. They are considered primary consumers.
Is there a biosphere 1?
The first mission in Biosphere 2 (so named because, technically, Earth is “Biosphere 1”) was highly publicized. Eight brave crew members locked themselves in the Biosphere for two years, determined to survive on their own with no outside help.

What is a trophic level?
A trophic level is the group of organisms within an ecosystem which occupy the same level in a food chain. There are five main trophic levels within a food chain, each of which differs in its nutritional relationship with the primary energy source.
The first trophic level contains only plants or other producers. Animals are consumers that must get food from eating other organisms. The second trophic level contains herbivores. The third trophic level contains carnivores that eat herbivores.
What is a real-life example of a trophic cascade?
A real-life example of a trophic cascade happened in 1986. The officials in Venezuela dammed the Caroni River and created an enormous lake. A lot of hilltops were turned into islands in this lake. As a result of the degradation of their habitats to tiny islands, many terrestrial predators experienced food scarcity.
