All food chains start with energy from the sun. … Thus the living part of a food chain always starts with plant life and ends with
an animal
. Plants are called producers because they are able to use light energy from the sun to produce food (sugar) from carbon dioxide and water.
What does a food chain always start with?
Producers and consumers
A food chain always starts with
a producer
. This is an organism that makes its own food. Most food chains start with a green plant, because plants can make their food by photosynthesis. A living thing that eats other plants and animals is called a consumer.
What is at the end of every food chain?
Detritivores and decomposers
are the final part of food chains. Detritivores are organisms that eat nonliving plant and animal remains. For example, scavengers such as vultures eat dead animals.
Who is at the top end of a food chain?
Therefore, it is not surprising that in our competitive “dog-eat-dog” society,
individuals who are considered successful
are seen as being at the top of the food chain, consuming all others for their benefit, whereas the less successful are seen as being at the bottom. Figure 1.

10. Which of the following condition is true about food chain? Explanation: In a food chain,
the organisms provide food for succeeding organisms irrespective whether they are producers or consumers
.
Which is the correct food chain?
The process of transfer of energy from producers through a series of organisms, i.e., from primary consumers to secondary consumers and from secondary consumers to tertiary consumers by process of eating and being eaten constitute a food chain. The correct food chain is
phytoplankton >> zooplankton >> fish.

producers
, because they make their own food by converting sunlight through photosynthesis. They also act as food, providing energy for other organisms.
What is the difference between a food chain and a food web?
A food chain
follows one path of energy and materials between species
. A food web is more complex and is a whole system of connected food chains. In a food web, organisms are placed into different trophic levels. … Producers are autotrophs, meaning they produce their own food through photosynthesis or chemosynthesis.
What are the 2 main food webs on earth?
There are two types of food chains: the grazing food chain, beginning with autotrophs, and
the detrital food chain
, beginning with dead organic matter (Smith & Smith 2009).
Are humans at top of food chain?
It's a platitude that we've all heard dozens of times, whether to justify our treatment of other species or simply to celebrate a carnivorous lifestyle:
humans are the top of the food chain
. Ecologists, though, have a statistical way of calculating a species' trophic level—its level, or rank, in a food chain.
What are the 4 food chains?
On the blackboard, write the following headings:
Producers, Primary Consumers, Secondary Consumers, and Tertiary Consumers
. Ask students to name some species under each heading. Then demonstrate how to create a food chain, using some of the species listed.
What role do humans play in the food chain?
Humans are said to be at the top of the food chain because
they eat plants and animals of all kinds
but are not eaten consistently by any animals. The human food chain starts with plants. Plants eaten by humans are called fruits and vegetables, and when they eat these plants, humans are primary consumers.
Where are food chains found?
Producers, such as plants, are organisms that utilize solar or chemical energy to synthesize starch. All food chains must start with a producer. In the deep sea, food chains centered
on hydrothermal vents
and cold seeps exist in the absence of sunlight.
Which statement is correct wrt food chain?
Which statement is correct with respect to the food chain?
All the chains formed by nutritional relations is used to understand energy flow
.
What are examples of a food chain?
- Nectar (flowers) – butterflies – small birds – foxes.
- Dandelions – snail – frog – bird – fox.
- Dead plants – centipede – robin – raccoon.
- Decayed plants – worms – birds – eagles.
- Fruits – tapir – jaguar.
- Fruits – monkeys – monkey-eating eagle.
- Grass – antelope – tiger – vulture.
- Grass – cow – man – maggot.
