What is the most useless animal in world?

It's impossible to say that any animal is truly "useless." Every animal plays a role in its ecosystem, even if we don't fully understand it.

Here's why the concept of a "useless" animal is flawed:

* Ecosystem Interactions: Animals are interconnected in complex food webs. A seemingly "useless" animal might be a vital food source for predators or help control populations of other species.

* Decomposition and Nutrient Cycling: Even animals that don't appear to have a direct role in the food chain contribute to decomposition, breaking down organic matter and releasing nutrients back into the environment.

* Pollination and Seed Dispersal: Many animals, from insects to birds, play crucial roles in pollinating plants and dispersing seeds, which are essential for plant reproduction and biodiversity.

* Evolutionary Value: Even seemingly "useless" animals contribute to the diversity of life on Earth, which is valuable for its own sake and can provide us with future benefits we haven't yet discovered.

Instead of thinking about animals as "useless," it's more beneficial to appreciate the intricate web of life and the importance of every species.
