What species do humans depend on to survive?
People depend on plants for food, clean air, water, fuel, clothing, and shelter. Nearly all food webs begin with plants, the primary producers. During photosynthesis, green plants use sunlight to change carbon dioxide from the air and water into simple sugars made of carbon, hydrogen, and oxygen.
What organisms do human beings depend on?
The human population exploits and depends on many animal and plant species for food, mainly through agriculture, an essential component of human culture, but also by exploiting wild populations, notably of marine fish.
Which living organism is more in the world?
In terms of numbers of species, insects certainly represent the largest percentage of the world’s organisms. There are more than 1 million species of insects that have been documented and studied by scientists.
Which term refers to the ability to survive and reproduce?
The term “fitness” in evolutionary biology means the ability of an organism to pass on its genetic material to its offspring. Biological or “Darwinian” fitness is being able to live long enough to reproduce and keep the population or species alive.
What are the 5 species humans need to survive?

How reliant are humans on relationships with other organisms?
Humans live in closely interdependent relationships with numerous other living organisms. Humans raise bees, who pollinate fruit and vegetable blossoms and provide honey. These are examples of exploitative symbiosis, where the plants and animals are used primarily for human benefits.
What was the biggest thing to live on Earth?
the blue whale
Share: Far bigger than any dinosaur, the blue whale is the largest known animal to have ever lived. An adult blue whale can grow to a massive 30m long and weigh more than 180,000kg – that’s about the same as 40 elephants, 30 Tyrannosaurus Rex or 2,670 average-sized men.
Are humans the most populated mammal?
Some mammals are so prevalent they cannot be accurately counting, such as rats, mice and bats….Most Populous Animals On Earth.
| Rank | Animal | Population |
|---|---|---|
| 1 | Human | 7,658,000,000 |
| 2 | Cows | 1,460,000,000 |
| 3 | Domestic pig | 1,000,000,000 |
| 4 | Domestic sheep | 1,000,000,000 |
What is the ability of an organism to survive in comparison to like species?
Evolutionary adaptation, or simply adaptation, is the adjustment of organisms to their environment in order to improve their chances at survival in that environment.
What organism Cannot reproduce?
A virus is a microscopic particle that can infect the cells of a biological organism. Viruses can only replicate themselves by infecting a host cell and therefore cannot reproduce on their own.
Do humans have to reproduce to live a long life?
The question is vague in some ways. A person does not have to reproduce in order to live a long life. Individual survival does not depend on reproduction. If the survival in question is that of the human species, then it’s both.
Does individual survival depend on reproduction or on death?
Individual survival does not depend on reproduction. If the survival in question is that of the human species, then it’s both. Basic math shows that in order for a population to remain stable, it needs an equal number of births to deaths to maintain its population.
What is the purpose of organisms in surviving or reproducing?
Organisms have no more “purpose” in surviving or reproducing than volcanoes have the “purpose” of erupting every now and then, or that riverbeds have the “purpose” of driving the flow of water over a geographical area.
Which characteristics of the organism(s) survive into the offspring lineage?
The characteristics of the organism (s) that breed (s) the most successfully, survive into the offspring lineage. The less an organism breeds, the fewer of the upstream lineage’s characteristics make it to downstream lineage. An organism’s purpose is to survive.
