Chapter 1: Plant Needs & Energy in Ecosystems - Comprehensive Digital Assessment (2)

Science - Primary 5 Unit 1: Energy Flow in Ecosystems & Living Systems

Standardized Milestone Assessment 2

Comprehensive summative assessment evaluating mastery of Unit 1 concepts across plant anatomy, photosynthesis, trophic levels, and ecosystem conservation.

Milestone 1 of 4 Round 1: Launch Questions (1 - 5)

Question 1 of 20 1 Mark

Which gas is absorbed by plant leaves from the atmosphere during daytime photosynthesis?

Methane

Nitrogen

Carbon dioxide (CO₂)

Oxygen

Question 2 of 20 1 Mark

What is the primary difference between xylem and phloem vascular tissues in plants?

Xylem absorbs sunlight; phloem releases oxygen

Xylem produces seeds; phloem produces pollen

Xylem carries food downward; phloem carries water upward

Xylem carries water upward; phloem carries manufactured food throughout the plant

Question 3 of 20 1 Mark

Which statement accurately describes seed germination in soil versus on a moist paper towel during the first 3 days?

Both sets of seeds germinate at nearly identical rates using energy stored inside their cotyledons

Seeds on paper towels turn immediately into mushrooms

Seeds on paper towels cannot germinate at all

Seeds in soil germinate 10 times faster than on paper towels

Question 4 of 20 1 Mark

What is an animal that feeds on the dead carcasses of animals it did not hunt itself called?

Scavenger

Herbivore

Producer

Apex predator

Question 5 of 20 1 Mark

Why does an aquatic plant (like Elodea) placed under bright light produce continuous gas bubbles?

It is actively performing photosynthesis and liberating oxygen gas

It is dissolving into air

It is boiling the water with solar heat

It is releasing carbon dioxide from rotting leaves

Question 6 of 20 1 Mark

What is the primary structural role of plant stems?

To release honey into the soil

To hide underground away from sunlight

To absorb water from deep bedrock

To support foliage and branches while conducting fluids via vascular bundles

Question 7 of 20 1 Mark

What happens if a keystone predator (like the sea otter) is completely removed from a marine food web?

All ocean water turns into freshwater

Fish begin flying in the air

Its prey (sea urchins) multiply unchecked, devouring all kelp and destroying the habitat

The ecosystem becomes completely free of any predators and flourishes forever

Question 8 of 20 1 Mark

Which of the following is a NON-BASIC need that can be substituted in modern agricultural systems?

Sunlight

Natural soil

Water

Carbon dioxide

Question 9 of 20 1 Mark

In the food chain: Plant → Aphid → Ladybug → Spider → Small Bird, which organism is the tertiary consumer?

Plant

Ladybug

Aphid

Spider

Question 10 of 20 1 Mark

What tiny plastic fragments (< 5mm) are ingested by marine filter feeders, polluting marine food chains?

Coral polyps

Diatoms

Mineral crystals

Microplastics

Question 11 of 20 1 Mark

What is the primary product synthesized by plants that stores chemical energy?

Chlorophyll

Carbon dioxide

Water

Glucose sugar

Question 12 of 20 1 Mark

Which of the following represents a biotic factor in an Egyptian river ecosystem?

Riverbed gravel

Water temperature

Tilapia fish

Sunlight intensity

Question 13 of 20 1 Mark

How do guard cells protect a plant during a severe midday desert heatwave?

They cause stomata to close, preventing fatal water loss via transpiration

They produce ice cubes inside the stem

They turn all leaves into flowers

They dig deeper roots into the rock

Question 14 of 20 1 Mark

What term describes the natural dynamic balance where living communities interact sustainably with their environment?

Ecosystem balance

Coral bleaching

Erosion

Overfishing

Question 15 of 20 1 Mark

What do plants do with excess glucose that is not needed for immediate energy?

They turn it into pure gold

They exhale it as carbon dioxide through stomata

They store it as insoluble starch in roots, stems, or seeds

They burn it into volcanic ash

Question 16 of 20 1 Mark

Which animal group is adapted to feed exclusively on the flesh of other organisms?

Autotrophs

Producers

Herbivores

Carnivores

Question 17 of 20 1 Mark

What is the primary benefit of establishing protected areas like Nabq and Ras Mohammed in Egypt?

To protect rich biodiversity, fragile coral reefs, and marine nursery habitats

To allow unlimited commercial trawling

To clear mangrove forests for factories

To replace natural beaches with asphalt

Question 18 of 20 1 Mark

In a food web diagram, what do the interconnected arrows represent?

The flight paths of migratory birds

The boundaries of national parks

The flow of energy and nutrients as one organism is consumed by another

Paths of wind currents

Question 19 of 20 1 Mark

Why do pine trees have slender needle-like leaves with waxy coatings?

To catch falling snow for food

To swim in deep ocean waters

To attract honeybees in winter

To minimize water loss through transpiration in cold, dry, or windy environments

Question 20 of 20 1 Mark

What happens to the chemical energy stored in plant glucose when an herbivorous gazelle eats the plant?

It is destroyed and converted into empty space

It turns back into sunlight rays shining from the gazelle's eyes

It converts into granite rock inside the stomach

It is transferred to the gazelle, fueling its cellular metabolism, movement, and body warmth
