Part 4. Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.
An ecosystem is a complex web of interconnected living organisms and their physical
environment. It includes all the plants, animals, and microorganisms in a given area, as well as
the non-living components such as soil, water, and air. Ecosystems can be as small as a pond or
as vast as a rainforest, but in each case, there is a delicate balance that allows life to thrive.
Producers, such as plants and algae, harness energy from the sun through photosynthesis,
converting it into food. These producers form the foundation of the food chain, as herbivores
consume them, and in turn, carnivores prey on herbivores. This interconnectedness creates a
balance where each species plays a vital role in maintaining the ecosystem's health. However,
human activities and environmental changes can disrupt this equilibrium. Deforestation,
pollution, and climate change are threatening ecosystems worldwide. The loss of biodiversity,
the variety of life within an ecosystem, is a concerning consequence. As species disappear, the
stability of the ecosystem is compromised, affecting everything within it, including humans who
depend on these systems for resources. Conservation efforts and sustainable practices are crucial
to preserving ecosystems. By understanding the intricate relationships within these systems, we
can work towards a harmonious coexistence with nature, ensuring the well-being of the planet
and all its inhabitants.
Question 1. What is the definition of an ecosystem?
A. group of animals

Question 3. In the given passage, what is a synonym for the word "foundation"?
A. transformation B. basis C. connection D. conservation
Question 4. What role do carnivores play in the ecosystem?
A. They produce food B. They prey on herbivores
C. They conduct photosynthesis D. hey are primary consumers
Question 5. What is the main idea of the passage?
A. The delicate balance in ecosystems and the importance of human intervention.
B. The interconnectedness of species in ecosystems and the threat posed by human
C. The process of photosynthesis and its significance in maintaining ecosystem health.
D. The consequences of environmental changes on the stability of ecosystems and the need
for conservation efforts.
