Understanding ecosystems and biodiversity

00:04.480 --> 00:11.480
Ecosystems are communities where living things interact with their environment.

00:11.480 --> 00:17.400
They include biotic components, like plants and animals, and abiotic components, like

00:17.400 --> 00:20.080
air, water, and minerals.

00:20.080 --> 00:28.920
For example, a desert ecosystem in Saudi Arabia features sand dunes, cacti, and lizards.

00:28.920 --> 00:32.920
The sea refers to the variety of life within an ecosystem.

00:32.920 --> 00:38.800
It includes all the different species of plants, animals, and microorganisms, as well as

00:38.800 --> 00:42.160
the genetic differences within these species.

00:42.160 --> 00:48.400
The Red Sea's coral reefs are a great example of biodiversity, hosting diverse marine

00:48.400 --> 00:53.120
lives such as colorful fish, corals, and algae.

00:53.120 --> 00:58.640
Each species contributes to the reef's health and balance, strengthening the ecosystem

00:58.640 --> 01:00.640
and supporting various forms of life.
