It is the circle of life.

They reproduce only because of their sexual interest. Different from us, animals and plants don't have programming minds. They don't think of an outcome of something, they do because it's in their nature. Like humans animals are interested in sexual intercourse so the results are that they reproduce, of course it's the same as human for the mother and child relation in animals too. In the case of plants, it's only in their nature. They don't even have desire to reproduce. The seeds are either spread by the wind or insects on the female plant and it reproduces, so the plant itself doesn't make any decisions in this process. Also, there are plants that have both genders, meaning that the male and female organs are both in the same plant, so it reproduces in it's nature of growing.

Hold on, it's not that simple. Take a simple plant for example. It needs the availability of water, nutrients, carbon dioxide, the absence of harmful materials, and a reasonable temperature. It must operate as an autonomous factory, drawing water-soluble nutrients up a stem that it's building as it goes. Then it performs a complex chemical process to produce glucose (C6H12O6) and oxygen. Meanwhile, it's using primarily that glucose to synthesize its own physical structure, converting the glucose to cellulose and many other materials. These materials have innumerable useful properties for healing, food flavoring, and so on. The process uses various forms of chlorophyll (C55H72O5N4Mg for example), which it must also synthesize as it goes.
Then it must synthesize a separate capsule and pack all of the information needed to repeat this process into a single DNA strand and package it with protection and starter food so it can be simply dropped on the ground and turn into another factory like itself, all by itself.
For the species to survive, every step of this process needs to work and to keep working. I find it impossible to believe that all this happened by accident, over and over again.

In order for organisms to even exist, they must have, and use, the ability to reproduce. Organisms have a realatively short lifespan, so survival requires passing their genes on to future generations.

Read the book 'Genome' by Matt Ridley. The cells need to reproduce themselves to ensure survivality of the genes, ie. DNA.

If animals and plants wouldnt reproduce, then there wouldnt be any plants or animals. Its survival of the species.

Every living species needs to reproduce to prevent the extinction of their species.
If one species dies, then the whole food chain gets thrown out of balance.

Absolutely in our programming. We reproduce to survive.

The same reason why we do. It's called survival. Every living thing has the drive to survive.

Because it is the only way to be immortal. The definition of fitness in the natural world is "survival of progeny".

look at the universe
filled with cycles and circles
we too are a cycle and a circle
just like plants(we are animals just an evolved form)
