How old is the oldest living organism?
Approximately 5,000 yearsSINGLE TREE: Approximately 5,000 years Methuselah, a bristlecone pine in the White Mountains of California, stands at the ripe old age of about 5,000, making it the oldest known non-cloned organism on Earth..
What are the 4 parts of a food chain?
The food chain is made up of four main parts – the sun, producers, consumers, and decomposers. Producers include all green plants. They use energy from the sun to make food. Consumers do not make their own food; they eat other plants or animals.
What is food chain and example?
A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected. eg: A hawk might also eat a mouse, a squirrel, a frog or some other animal.
What came first bacteria or virus?
Viruses did not evolve first, they found. Instead, viruses and bacteria both descended from an ancient cellular life form. But while – like humans – bacteria evolved to become more complex, viruses became simpler.
Which is true of a food chain?
Explanation: In a food chain, the organisms provide food for succeeding organisms irrespective whether they are producers or consumers. Plants which are producer gives energy to the primary consumers like deer and this deer gives energy to secondary consumer say carnivores.
What is food chain with diagram?
Normally, food webs consist of a number of food chains meshed together. Each food chain is a descriptive diagram including a series of arrows, each pointing from one species to another, representing the flow of food energy from one feeding group of organisms to another.
What is food chain types?
The transfer of food energy from the producers, through a series of organisms (herbivores to carnivores to decomposers) with repeated eating and being eaten, is known as food chain. … In nature, basically two types of food chains are recognized – grazing food chain and detritus food chain.
Can any food chain be complete without plants?
No. Explanation: Because the living of the food chain always starts with plants life and ends with animals life. Plants are called producers because they are able to use light energy from the sun, carbon dioxide and water to produce food.
What is the first organism?
BacteriaBacteria have been the very first organisms to live on Earth. They made their appearance 3 billion years ago in the waters of the first oceans. At first, there were only anaerobic heterotrophic bacteria (the primordial atmosphere was virtually oxygen-free).
What is a food chain explain with 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.
What is a simple food chain?
A food chain shows the feeding relationship between different organisms in a particular environment and/or habitat. … Food chains show how energy is passed from the sun to producers, from producers to consumers, and from consumers to decomposes such as fungi. They also show how animals depend on other organisms for food.
How did life appear on Earth?
The earliest known life-forms are putative fossilized microorganisms, found in hydrothermal vent precipitates, that may have lived as early as 4.28 Gya (billion years ago), relatively soon after the oceans formed 4.41 Gya, and not long after the formation of the Earth 4.54 Gya.
What is the 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 is a food chain start with?
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 the most important organism in a food chain?
hands down the most important organism on this planet is marine algae.” Phytoplankton are tiny microscopic plants – algae – that form the base of the marine food chain. Phytoplankton is most abundant in colder waters where there is an abundance of nutrients.
