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.
What is an accurate food chain?
The
scientific understanding of a food chain
is more precise than in its everyday usage. In ecology, a food chain is a linear sequence of organisms through which nutrients and energy pass: primary producers, primary consumers, and higher-level consumers are used to describe ecosystem structure and dynamics.
What is the correct order of the food chain?
The order of a food chain looks like this:
sun (or light energy), primary producers, primary consumers, secondary consumers, and tertiary consumers
.
What are the 5 food chains?
- 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.
Which is true of a food chain Mcq?
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
.
What comes first in a food chain?
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. Nearly all autotrophs use a process called photosynthesis to create “food” (a nutrient called glucose) from sunlight, carbon dioxide, and water.
What are the 4 parts of a food chain?
All food chains begin with energy from the sun. The food chain is made up of four main parts –
the sun, producers, consumers, and decomposers
. Producers include all green plants.
What is food chain and diagram?
A food chain is
a linear diagram showing how energy moves through an ecosystem
. It shows only one pathway out of the many possibilities in a specific ecosystem. BiologyFood Chain.
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).
Where does food chain start?
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 food chain and example?
The definition of a food chain is a system where a small animal is the food for a larger animal which, in turn, is the food for an even larger animal. An example of food chain is
a fly being eaten by a frog
and then the frog is eaten by a larger animal. noun.
What is the shortest food chain?
The shortest food chains consist of
a producer and a decomposer
. Animals get energy from the food they eat, and all living things get food from energy from food.
What are plants called in a food chain?
Plants form the base of Great Lakes food chains. They're called
producers
, because they make their own food by converting sunlight through photosynthesis. They also act as food, providing energy for other organisms.
Are humans part of 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.
What always ends a food chain?
A food chain always starts with plant life and ends
with an animal
. … The process by which plants make food is called photosynthesis. Animals cannot make their own food so they must eat plants and/or other animals. They are called consumers.
What is the primary source of energy in a food web?
3.1
The Sun
is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs.
