Question

1. give an example of how the organisms carry out these processes. some of them have been done for you.

life process	tiger	apple tree
respiration
sensitivity		uses hormones to sense direction of gravity so roots grow downwards.
growth
reproduction	uses sexual reproduction to produce offspring known as \cubs\.
excretion
nutrition

Explanation:

To solve this, we analyze each life process for tiger (animal) and apple tree (plant):

Movement

• Tiger: Uses muscles and limbs to run/hunt.
• Apple tree: Stems grow towards light (phototropism), roots towards water (hydrotropism).

Respiration

• Tiger: Uses lungs to breathe (aerobic respiration: $C_6H_{12}O_6 + 6O_2

ightarrow 6CO_2 + 6H_2O + \text{energy}$).

• Apple tree: Uses stomata in leaves for gas exchange (aerobic respiration in cells).

Sensitivity

• Tiger: Uses eyes/ears/nose to detect prey/danger (e.g., sees deer to hunt).

Growth

• Tiger: Cells divide/grow; cubs grow into adults (muscle/bone development).
• Apple tree: Cells divide; trunk thickens, branches/leaves grow (photosynthesis fuels growth).

Reproduction (Apple tree)

• Uses sexual reproduction: Flowers (stamens/pistils) for pollination → fruit with seeds (offspring).

Excretion

• Tiger: Kidneys excrete urea (urine); lungs excrete $CO_2$.
• Apple tree: Excretes oxygen (photosynthesis byproduct) and stores waste in leaves/fruits (sheds leaves).

Nutrition

• Tiger: Heterotroph; hunts (e.g., deer) → digests food for energy.
• Apple tree: Autotroph; photosynthesis: $6CO_2 + 6H_2O \xrightarrow{\text{light}} C_6H_{12}O_6 + 6O_2$ (uses sunlight, $CO_2$, $H_2O$).

Filling the table (example rows):

Life Process	Tiger	Apple tree
Respiration	Breathes via lungs (aerobic respiration).	Uses stomata for gas exchange (aerobic respiration).
Sensitivity	Detects prey with eyes/ears.	(Given: Uses hormones to sense gravity for roots.)
Growth	Cubs grow into adult tigers (cell division).	Trunk thickens, leaves grow (photosynthesis).
Reproduction	(Given: Sexual reproduction, produces cubs.)	Uses flowers for pollination → seeds in fruits.
Excretion	Excretes urea (urine) via kidneys.	Excretes oxygen (photosynthesis) and stores waste in leaves.
Nutrition	Hunts deer (heterotrophic nutrition).	Photosynthesizes (autotrophic nutrition: $6CO_2 + 6H_2O \xrightarrow{\text{light}} C_6H_{12}O_6 + 6O_2$).

(Note: The table can be completed with these examples for each process.)
