Aquatic Ecosystems vs. Terrestrial Biomes: Understanding the Differences
Aquatic ecosystems and terrestrial biomes are two very different types of environments on Earth. Each one has its own special features, living things, and how those living things interact. Knowing these differences is important, especially for Year 10 geography classes, where we study ecosystems and biomes like deserts, forests, and tundras.
Aquatic Ecosystems
Aquatic ecosystems are mainly found in water. They can be divided into two main types: freshwater and marine.
The physical features of these ecosystems, like how salty the water is, how deep it is, how fast it flows, and the temperature, affect what kinds of living things can survive there. For example, ocean waters are salty, making them home to saltwater creatures like fish, seaweed, and crabs. Freshwater places, which have less salt, are better for other types of animals and plants.
Terrestrial Biomes
On the other hand, terrestrial biomes are found on land. They are defined by their weather conditions, soil types, and plant life. Some examples of terrestrial biomes are:
Each biome has specific temperatures and rainfall patterns, which determine what plants and animals can live there. Deserts have little rain and big temperature changes, so plants like cacti and animals like camels have learned to save water. In contrast, forests, especially temperate and tropical ones, receive a lot of rain and have many kinds of plants, including trees and bushes, which support many different animals.
Food Webs
In these ecosystems, there are also big differences in living things, or biotic factors. In aquatic ecosystems, tiny organisms called plankton (both phytoplankton and zooplankton) make up the base of the food web. These tiny creatures support larger animals like fish and whales.
In terrestrial ecosystems, you can see food webs more clearly. For example, plants like grasses and trees form the base of the food chain, which leads to animals that eat them, all the way up to top predators.
Movement of Organisms
How creatures move in these ecosystems is different too. Aquatic organisms have adapted to swim or float with water currents. Their ability to move depends on both their bodies and how the water flows.
In contrast, land animals have evolved to walk, run, or fly, allowing them to dodge obstacles on land more easily.
Impact of Human Activity
Human activities affect both types of ecosystems in different ways. For example:
Both ecosystems suffer from these actions, leading to a loss of species and unbalancing food webs.
Nutrient Cycling
Nutrients, the essential substances that living things need to grow, move through these ecosystems in different ways. In terrestrial ecosystems, they are mostly recycled when dead plants and animals break down in the soil, helped by creatures like worms and fungi.
In aquatic systems, nutrients are often found in layers of sediment at the bottom or mixed through the water. The flow of water can move these nutrients around, affecting where they are available. Freshwater nutrients can change by season, while ocean nutrients are usually more stable but can be low in some areas.
Climate Influence
Weather also shapes these ecosystems, but in different ways.
In terrestrial ecosystems, temperature and rainfall affect everything from how plants grow to how animals adapt. For example, trees in temperate forests may lose their leaves in winter to save water, and some animals might move away for the winter or hibernate.
In aquatic ecosystems, temperature changes less throughout the year. However, water movements can influence oxygen levels and how much light penetrates, which affects how plants and animals grow.
Adaptations of Organisms
Creatures in each environment have also changed over time to survive better. Aquatic creatures, like fish, have streamlined bodies to swim efficiently and gills to breathe underwater.
Land animals, however, have developed different traits, like thick bark on trees to protect against harsh weather or deep roots to access water underground.
Biodiversity
Biodiversity means the variety of living things in an area. Aquatic and terrestrial ecosystems are both home to diverse life, reflecting how different organisms adapt to their environments. Oceans may have concentrated biodiversity in spots like coral reefs, while land biomes display diversity in the different plant layers, supporting many animal species.
Succession Processes
Another difference is in how these ecosystems change over time, known as succession. In land ecosystems, succession can move through stages, from simple plants growing after a disturbance to a mature forest. In aquatic systems, freshwater lakes and rivers might experience succession through processes like eutrophication, where too many nutrients lead to algae growth, changing the ecosystem.
Conclusion
In conclusion, aquatic ecosystems and terrestrial biomes are very different, each with its own characteristics shaped by their environment, living things, and evolution. Understanding these differences helps us appreciate their importance in our world. Protecting both types of ecosystems is essential, as they provide vital functions for our planet and support many forms of life. As humans continue to impact these ecosystems, it is crucial to engage in sustainable practices to keep them healthy and thriving. Each ecosystem plays a key role in the complex web of life on Earth.
