Ecosystem:
- The Earth is home to plants and animals.
- The natural surroundings in which a living thing survives is its environment.
- These living things interact with one another and with their surroundings. This interaction of the living things with their physical environment forms an ecosystem.
- Common examples of ecosystems are pond, lake, river, marine, desert, grassland and forest ecosystems.
Heterotrophs:
- All living organisms that cannot make their own food either depend on plants or other animals for food.
- They are called heterotrophs.
Consumers:

Some examples of herbivores are cows, goats and deer. Herbivores are also called primary consumers.
- Secondary consumers: Animals that eat the flesh and meat of other living animals are called carnivores. Some examples of carnivores are lions, tigers and leopards. Carnivores that eat herbivores are also called secondary consumers.
- Tertiary consumers: There are certain carnivores that eat other carnivores. They are called tertiary consumers.
- Some animals eat both plants and animals. They are called omnivores. Some examples of omnivores are human beings, monkeys and bears.
- Some animals feed on dead animals. They are called scavengers. Vultures are the most common scavengers.
- Some organisms derive their nutrition by breaking down dead and decaying material. They are also referred to as the cleaners of the environment. These organisms are called decomposers.

As an environmental science enthusiast with a deep understanding of ecosystems, let's delve into the intricacies of the concepts mentioned in the provided article.
Ecosystem: The term "ecosystem" refers to a complex and interconnected system where living organisms interact with each other and their physical environment. Ecosystems can take various forms, and the examples provided—ponds, lakes, rivers, marine environments, deserts, grasslands, and forests—illustrate the diversity of these systems on Earth. Each ecosystem has its unique set of plants, animals, and environmental conditions, creating a delicate balance of interdependence.
Heterotrophs: Heterotrophs are organisms that cannot produce their own food and, therefore, rely on other organisms for nutrition. In the context of ecosystems, heterotrophs play a crucial role in energy transfer, as they obtain their sustenance by consuming other living organisms.
Consumers: Consumers are a key component of ecosystems, categorized based on their dietary habits.
-
Primary Consumers (Herbivores): Herbivores are animals that primarily feed on plants. Examples include cows, goats, and deer. They are often referred to as primary consumers because they occupy the first trophic level in the food chain, directly consuming producers (plants).
-
Secondary Consumers (Carnivores): Carnivores are animals that consume the flesh and meat of other living animals. Lions, tigers, and leopards are examples of carnivores. When carnivores feed on herbivores, they are termed secondary consumers, occupying a higher trophic level in the food chain.
-
Tertiary Consumers: Tertiary consumers are carnivores that eat other carnivores, occupying an even higher trophic level. This level of the food chain highlights the complexity of energy transfer in ecosystems.
-
Omnivores: Some animals have a diet that includes both plants and animals, making them omnivores. Humans, monkeys, and bears are examples of omnivores, showcasing adaptability in dietary habits.
-
Scavengers: Scavengers are organisms that feed on dead animals. Vultures are a notable example of scavengers, playing a vital role in cleaning up carrion and preventing the spread of diseases.
-
Decomposers: Decomposers are organisms that break down dead and decaying material, recycling nutrients back into the ecosystem. These organisms act as the cleaners of the environment, promoting the decomposition of organic matter. They play a crucial role in maintaining the balance of ecosystems by recycling nutrients and facilitating the continuous flow of energy through the food web.
In summary, the concepts of ecosystems, heterotrophs, and consumers are fundamental to understanding the intricate web of life on Earth and the dynamic relationships that sustain our planet's biodiversity.
